Mojibake ( 文字化け ; IPA: [mod͡ʑibake]) is the garbled text that is the result of text being decoded using an unintended graphic symbol encoding.[1] The result is a systematic replacement of symbols with completely unrelated ones, often from a different writing system.
This display may include the generic replacement character ("�") in places where the binary representation is considered invalid. A replacement can also involve multiple consecutive symbols, every bit viewed in one encoding, when the same binary code constitutes one symbol in the other encoding. This is either because of differing constant length encoding (as in Asian 16-bit encodings vs European viii-bit encodings), or the use of variable length encodings (notably UTF-8 and UTF-16).
Failed rendering of glyphs due to either missing fonts or missing glyphs in a font is a different issue that is not to exist confused with mojibake. Symptoms of this failed rendering include blocks with the code bespeak displayed in hexadecimal or using the generic replacement character. Importantly, these replacements are valid and are the result of correct mistake handling by the software.
Etymology [edit]
Mojibake means "graphic symbol transformation" in Japanese. The word is composed of 文字 (moji, IPA: [mod͡ʑi]), "grapheme" and 化け (bake, IPA: [bäke̞], pronounced "bah-keh"), "transform".
Causes [edit]
To correctly reproduce the original text that was encoded, the correspondence between the encoded data and the notion of its encoding must be preserved. As mojibake is the example of not-compliance betwixt these, it can be accomplished past manipulating the data itself, or just relabeling it.
Mojibake is frequently seen with text information that have been tagged with a wrong encoding; information technology may not even be tagged at all, but moved betwixt computers with different default encodings. A major source of trouble are advice protocols that rely on settings on each computer rather than sending or storing metadata together with the data.
The differing default settings between computers are in part due to differing deployments of Unicode among operating arrangement families, and partly the legacy encodings' specializations for different writing systems of human languages. Whereas Linux distributions mostly switched to UTF-8 in 2004,[ii] Microsoft Windows by and large uses UTF-sixteen, and sometimes uses 8-bit code pages for text files in different languages.[ dubious ]
For some writing systems, an example being Japanese, several encodings accept historically been employed, causing users to see mojibake relatively ofttimes. As a Japanese example, the word mojibake "文字化け" stored as EUC-JP might be incorrectly displayed as "ﾊｸｻ�ｽ､ｱ", "ﾊｸｻ嵂ｽ､ｱ" (MS-932), or "ﾊｸｻ郾ｽ､ｱ" (Shift JIS-2004). The same text stored as UTF-8 is displayed equally "譁�蟄怜喧縺�" if interpreted as Shift JIS. This is farther exacerbated if other locales are involved: the same UTF-8 text appears as "æ–‡å—化ã'" in software that assumes text to be in the Windows-1252 or ISO-8859-1 encodings, usually labelled Western, or (for example) as "鏂囧瓧鍖栥亼" if interpreted as being in a GBK (Mainland China) locale.
| Original text | 文 | 字 | 化 | け | ||||
|---|---|---|---|---|---|---|---|---|
| Raw bytes of EUC-JP encoding | CA | B8 | BB | FA | B2 | BD | A4 | B1 |
| Bytes interpreted every bit Shift-JIS encoding | ﾊ | ｸ | ｻ | 郾 | ｽ | ､ | ｱ | |
| Bytes interpreted as ISO-8859-1 encoding | Ê | ¸ | » | ú | ² | ½ | ¤ | ± |
| Bytes interpreted as GBK encoding | 矢 | 机 | 步 | け | ||||
Underspecification [edit]
If the encoding is not specified, it is up to the software to decide it by other means. Depending on the type of software, the typical solution is either configuration or charset detection heuristics. Both are prone to mis-prediction in not-so-uncommon scenarios.
The encoding of text files is affected by locale setting, which depends on the user'south language, brand of operating arrangement and maybe other conditions. Therefore, the assumed encoding is systematically wrong for files that come from a estimator with a unlike setting, or even from a differently localized software within the aforementioned system. For Unicode, one solution is to use a byte order mark, but for source code and other auto readable text, many parsers don't tolerate this. Another is storing the encoding as metadata in the file organization. File systems that support extended file attributes can store this as user.charset.[3] This also requires support in software that wants to take reward of information technology, merely does non disturb other software.
While a few encodings are piece of cake to detect, in particular UTF-eight, at that place are many that are difficult to distinguish (encounter charset detection). A web browser may non be able to distinguish a page coded in EUC-JP and another in Shift-JIS if the coding scheme is non assigned explicitly using HTTP headers sent along with the documents, or using the HTML document'south meta tags that are used to substitute for missing HTTP headers if the server cannot be configured to send the proper HTTP headers; run into graphic symbol encodings in HTML.
Mis-specification [edit]
Mojibake also occurs when the encoding is wrongly specified. This often happens between encodings that are similar. For case, the Eudora e-mail customer for Windows was known to send emails labelled as ISO-8859-ane that were in reality Windows-1252.[four] The Mac Bone version of Eudora did non showroom this behaviour. Windows-1252 contains extra printable characters in the C1 range (the most frequently seen beingness curved quotation marks and actress dashes), that were non displayed properly in software complying with the ISO standard; this especially affected software running nether other operating systems such as Unix.
Human ignorance [edit]
Of the encodings still in utilize, many are partially compatible with each other, with ASCII as the predominant common subset. This sets the stage for human being ignorance:
- Compatibility can exist a deceptive property, as the mutual subset of characters is unaffected past a mixup of two encodings (see Issues in different writing systems).
- People call up they are using ASCII, and tend to label whatsoever superset of ASCII they actually use as "ASCII". Maybe for simplification, but even in academic literature, the give-and-take "ASCII" tin exist found used as an case of something not compatible with Unicode, where evidently "ASCII" is Windows-1252 and "Unicode" is UTF-8.[1] Note that UTF-8 is backwards compatible with ASCII.
Overspecification [edit]
When in that location are layers of protocols, each trying to specify the encoding based on different information, the least certain information may exist misleading to the recipient. For case, consider a spider web server serving a static HTML file over HTTP. The character set may be communicated to the client in any number of 3 ways:
- in the HTTP header. This information tin can be based on server configuration (for instance, when serving a file off disk) or controlled by the application running on the server (for dynamic websites).
- in the file, equally an HTML meta tag (
http-equivorcharset) or theencodingaspect of an XML announcement. This is the encoding that the author meant to salve the particular file in. - in the file, equally a byte order mark. This is the encoding that the author'south editor really saved it in. Unless an accidental encoding conversion has happened (past opening it in one encoding and saving information technology in another), this will be right. It is, nonetheless, only available in Unicode encodings such as UTF-8 or UTF-16.
Lack of hardware or software support [edit]
Much older hardware is typically designed to support but one graphic symbol fix and the character gear up typically cannot be contradistinct. The character tabular array contained inside the brandish firmware will be localized to have characters for the country the device is to be sold in, and typically the table differs from country to country. As such, these systems will potentially display mojibake when loading text generated on a system from a different state. Likewise, many early on operating systems do not support multiple encoding formats and thus volition terminate upward displaying mojibake if made to display non-standard text—early versions of Microsoft Windows and Palm OS for example, are localized on a per-country basis and volition only support encoding standards relevant to the state the localized version will exist sold in, and will display mojibake if a file containing a text in a different encoding format from the version that the OS is designed to support is opened.
Resolutions [edit]
Applications using UTF-eight equally a default encoding may achieve a greater caste of interoperability considering of its widespread use and backward compatibility with The states-ASCII. UTF-eight also has the ability to exist directly recognised by a unproblematic algorithm, so that well written software should exist able to avoid mixing UTF-8 up with other encodings.
The difficulty of resolving an instance of mojibake varies depending on the application within which information technology occurs and the causes of it. Two of the most mutual applications in which mojibake may occur are spider web browsers and give-and-take processors. Modern browsers and discussion processors often back up a wide array of character encodings. Browsers frequently let a user to change their rendering engine'southward encoding setting on the fly, while word processors permit the user to select the appropriate encoding when opening a file. It may take some trial and mistake for users to find the correct encoding.
The problem gets more complicated when it occurs in an application that usually does not back up a wide range of character encoding, such as in a not-Unicode computer game. In this example, the user must change the operating system's encoding settings to match that of the game. Nevertheless, irresolute the system-wide encoding settings can also crusade Mojibake in pre-existing applications. In Windows XP or later, a user also has the option to utilize Microsoft AppLocale, an application that allows the irresolute of per-awarding locale settings. Still, changing the operating system encoding settings is non possible on earlier operating systems such as Windows 98; to resolve this issue on before operating systems, a user would have to utilize third party font rendering applications.
Problems in dissimilar writing systems [edit]
English [edit]
Mojibake in English texts generally occurs in punctuation, such every bit em dashes (—), en dashes (–), and curly quotes (",",','), simply rarely in graphic symbol text, since near encodings concord with ASCII on the encoding of the English alphabet. For example, the pound sign "£" will appear equally "£" if it was encoded past the sender as UTF-8 but interpreted by the recipient as CP1252 or ISO 8859-1. If iterated using CP1252, this can atomic number 82 to "£", "£", "ÃÆ'‚£", etc.
Some computers did, in older eras, have vendor-specific encodings which caused mismatch as well for English text. Commodore brand viii-flake computers used PETSCII encoding, particularly notable for inverting the upper and lower instance compared to standard ASCII. PETSCII printers worked fine on other computers of the era, but flipped the case of all letters. IBM mainframes use the EBCDIC encoding which does non match ASCII at all.
Other Western European languages [edit]
The alphabets of the N Germanic languages, Catalan, Finnish, German, French, Portuguese and Spanish are all extensions of the Latin alphabet. The additional characters are typically the ones that become corrupted, making texts only mildly unreadable with mojibake:
- å, ä, ö in Finnish and Swedish
- à, ç, è, é, ï, í, ò, ó, ú, ü in Catalan
- æ, ø, å in Norwegian and Danish
- á, é, ó, ij, è, ë, ï in Dutch
- ä, ö, ü, and ß in German language
- á, ð, í, ó, ú, ý, æ, ø in Faroese
- á, ð, é, í, ó, ú, ý, þ, æ, ö in Icelandic
- à, â, ç, è, é, ë, ê, ï, î, ô, ù, û, ü, ÿ, æ, œ in French
- à, è, é, ì, ò, ù in Italian
- á, é, í, ñ, ó, ú, ü, ¡, ¿ in Spanish
- à, á, â, ã, ç, é, ê, í, ó, ô, õ, ú in Portuguese (ü no longer used)
- á, é, í, ó, ú in Irish
- à, è, ì, ò, ù in Scottish Gaelic
- £ in British English
… and their uppercase counterparts, if applicable.
These are languages for which the ISO-8859-1 character ready (as well known as Latin 1 or Western) has been in use. Even so, ISO-8859-1 has been obsoleted by ii competing standards, the backward compatible Windows-1252, and the slightly altered ISO-8859-15. Both add the Euro sign € and the French œ, but otherwise whatsoever confusion of these 3 character sets does not create mojibake in these languages. Furthermore, it is e'er safe to interpret ISO-8859-ane equally Windows-1252, and adequately safe to translate information technology every bit ISO-8859-fifteen, in detail with respect to the Euro sign, which replaces the rarely used currency sign (¤). Even so, with the advent of UTF-viii, mojibake has become more common in certain scenarios, e.g. commutation of text files between UNIX and Windows computers, due to UTF-8'south incompatibility with Latin-1 and Windows-1252. But UTF-eight has the ability to be directly recognised past a simple algorithm, and so that well written software should be able to avoid mixing UTF-viii up with other encodings, and so this was almost mutual when many had software not supporting UTF-8. Most of these languages were supported by MS-DOS default CP437 and other machine default encodings, except ASCII, and so issues when ownership an operating system version were less common. Windows and MS-DOS are not compatible however.
In Swedish, Norwegian, Danish and German, vowels are rarely repeated, and it is ordinarily obvious when one character gets corrupted, east.g. the second letter in "kärlek" ( kärlek , "love"). This fashion, fifty-fifty though the reader has to guess between å, ä and ö, almost all texts remain legible. Finnish text, on the other manus, does feature repeating vowels in words similar hääyö ("wedding night") which can sometimes return text very difficult to read (due east.1000. hääyö appears every bit "hääyö"). Icelandic and Faroese have ten and 8 possibly confounding characters, respectively, which thus can make it more hard to gauge corrupted characters; Icelandic words like þjóðlöð ("outstanding hospitality") get well-nigh entirely unintelligible when rendered equally "þjóðlöð".
In German, Buchstabensalat ("letter salad") is a common term for this phenomenon, and in Castilian, deformación (literally deformation).
Some users transliterate their writing when using a computer, either by omitting the problematic diacritics, or by using digraph replacements (å → aa, ä/æ → ae, ö/ø → oe, ü → ue etc.). Thus, an author might write "ueber" instead of "über", which is standard practice in German when umlauts are non bachelor. The latter practise seems to be better tolerated in the German language sphere than in the Nordic countries. For example, in Norwegian, digraphs are associated with archaic Danish, and may be used jokingly. Notwithstanding, digraphs are useful in communication with other parts of the world. Equally an example, the Norwegian football actor Ole Gunnar Solskjær had his name spelled "SOLSKJAER" on his back when he played for Manchester United.
An artifact of UTF-viii misinterpreted as ISO-8859-1, "Band meg nÃ¥" (" Ring meg nå "), was seen in an SMS scam raging in Norway in June 2014.[5]

| ISO 8859-one | Mac Roman | SmˆrgÂs |
| UTF-eight | ISO 8859-1 | Smörgås |
| UTF-8 | Mac Roman | Smörgås |
Central and Eastern European [edit]
Users of Key and Eastern European languages can also be affected. Considering near computers were non connected to any network during the mid- to late-1980s, there were dissimilar character encodings for every language with diacritical characters (run across ISO/IEC 8859 and KOI-viii), ofttimes besides varying by operating organisation.
Hungarian [edit]
Hungarian is some other affected language, which uses the 26 basic English characters, plus the accented forms á, é, í, ó, ú, ö, ü (all present in the Latin-1 character prepare), plus the two characters ő and ű, which are not in Latin-1. These 2 characters can be correctly encoded in Latin-ii, Windows-1250 and Unicode. Before Unicode became common in electronic mail clients, due east-mails containing Hungarian text oft had the messages ő and ű corrupted, sometimes to the signal of unrecognizability. Information technology is common to respond to an electronic mail rendered unreadable (see examples below) by grapheme mangling (referred to every bit "betűszemét", meaning "letter garbage") with the phrase "Árvíztűrő tükörfúrógép", a nonsense phrase (literally "Alluvion-resistant mirror-drilling machine") containing all accented characters used in Hungarian.

Polish [edit]
Prior to the creation of ISO 8859-ii in 1987, users of various calculating platforms used their own character encodings such as AmigaPL on Amiga, Atari Club on Atari ST and Masovia, IBM CP852, Mazovia and Windows CP1250 on IBM PCs. Shine companies selling early DOS computers created their ain mutually-incompatible ways to encode Polish characters and merely reprogrammed the EPROMs of the video cards (typically CGA, EGA, or Hercules) to provide hardware lawmaking pages with the needed glyphs for Smoothen—arbitrarily located without reference to where other computer sellers had placed them.
The state of affairs began to meliorate when, later force per unit area from academic and user groups, ISO 8859-2 succeeded as the "Cyberspace standard" with limited support of the dominant vendors' software (today largely replaced by Unicode). With the numerous problems acquired by the multifariousness of encodings, fifty-fifty today some users tend to refer to Polish diacritical characters every bit krzaczki ([kshach-kih], lit. "little shrubs").
Russian and other Cyrillic alphabets [edit]
Mojibake may exist colloquially chosen krakozyabry ( кракозя́бры [krɐkɐˈzʲæbrɪ̈]) in Russian, which was and remains complicated by several systems for encoding Cyrillic.[six] The Soviet Union and early on Russian federation developed KOI encodings ( Kod Obmena Informatsiey , Код Обмена Информацией , which translates to "Code for Information Exchange"). This began with Cyrillic-only vii-fleck KOI7, based on ASCII but with Latin and some other characters replaced with Cyrillic letters. So came 8-bit KOI8 encoding that is an ASCII extension which encodes Cyrillic letters only with high-scrap set up octets corresponding to seven-scrap codes from KOI7. It is for this reason that KOI8 text, even Russian, remains partially readable after stripping the eighth bit, which was considered as a major advantage in the age of 8BITMIME-unaware electronic mail systems. For case, words " Школа русского языка " shkola russkogo yazyka , encoded in KOI8 and then passed through the high bit stripping process, terminate up rendered every bit "[KOLA RUSSKOGO qZYKA". Eventually KOI8 gained different flavors for Russian and Bulgarian (KOI8-R), Ukrainian (KOI8-U), Belarusian (KOI8-RU) and even Tajik (KOI8-T).
Meanwhile, in the Westward, Code page 866 supported Ukrainian and Belarusian every bit well as Russian/Bulgarian in MS-DOS. For Microsoft Windows, Code Page 1251 added support for Serbian and other Slavic variants of Cyrillic.
Almost recently, the Unicode encoding includes code points for practically all the characters of all the earth'south languages, including all Cyrillic characters.
Before Unicode, it was necessary to friction match text encoding with a font using the same encoding system. Failure to exercise this produced unreadable gibberish whose specific appearance varied depending on the exact combination of text encoding and font encoding. For example, attempting to view non-Unicode Cyrillic text using a font that is limited to the Latin alphabet, or using the default ("Western") encoding, typically results in text that consists virtually entirely of vowels with diacritical marks. (KOI8 " Библиотека " ( biblioteka , library) becomes "âÉÂÌÉÏÔÅËÁ".) Using Windows codepage 1251 to view text in KOI8 or vice versa results in garbled text that consists mostly of capital letters (KOI8 and codepage 1251 share the aforementioned ASCII region, only KOI8 has uppercase letters in the region where codepage 1251 has lowercase, and vice versa). In general, Cyrillic gibberish is symptomatic of using the wrong Cyrillic font. During the early years of the Russian sector of the World Wide Spider web, both KOI8 and codepage 1251 were mutual. As of 2017, one can yet encounter HTML pages in codepage 1251 and, rarely, KOI8 encodings, also as Unicode. (An estimated one.seven% of all web pages worldwide – all languages included – are encoded in codepage 1251.[7]) Though the HTML standard includes the ability to specify the encoding for any given spider web page in its source,[8] this is sometimes neglected, forcing the user to switch encodings in the browser manually.
In Bulgarian, mojibake is often chosen majmunica ( маймуница ), meaning "monkey'southward [alphabet]". In Serbian, information technology is called đubre ( ђубре ), meaning "trash". Unlike the former USSR, South Slavs never used something similar KOI8, and Code Page 1251 was the dominant Cyrillic encoding there before Unicode. Therefore, these languages experienced fewer encoding incompatibility troubles than Russian. In the 1980s, Bulgarian computers used their own MIK encoding, which is superficially similar to (although incompatible with) CP866.

| UTF-eight | KOI8-R | п я─п╟п╨п╬п╥я▐п╠я─я▀ |
Yugoslav languages [edit]
Croation, Bosnian, Serbian (the dialects of the Yugoslav Serbo-Croatian language) and Slovene add together to the basic Latin alphabet the messages š, đ, č, ć, ž, and their capital counterparts Š, Đ, Č, Ć, Ž (only č/Č, š/Š and ž/Ž in Slovenian; officially, although others are used when needed, mostly in foreign names, equally well). All of these messages are defined in Latin-2 and Windows-1250, while simply some (š, Š, ž, Ž, Đ) exist in the usual OS-default Windows-1252, and are there because of some other languages.
Although Mojibake can occur with any of these characters, the letters that are not included in Windows-1252 are much more prone to errors. Thus, even nowadays, "šđčćž ŠĐČĆŽ" is often displayed as "šðèæž ŠÐÈÆŽ", although ð, è, æ, È, Æ are never used in Slavic languages.
When bars to bones ASCII (almost user names, for instance), common replacements are: š→s, đ→dj, č→c, ć→c, ž→z (capital forms analogously, with Đ→Dj or Đ→DJ depending on word case). All of these replacements introduce ambiguities, so reconstructing the original from such a course is commonly done manually if required.
The Windows-1252 encoding is important because the English versions of the Windows operating system are virtually widespread, not localized ones.[ citation needed ] The reasons for this include a relatively small and fragmented market, increasing the price of high quality localization, a loftier degree of software piracy (in turn caused by high price of software compared to income), which discourages localization efforts, and people preferring English versions of Windows and other software.[ commendation needed ]
The drive to differentiate Croation from Serbian, Bosnian from Croation and Serbian, and at present fifty-fifty Montenegrin from the other three creates many issues. There are many different localizations, using different standards and of unlike quality. There are no common translations for the vast amount of computer terminology originating in English language. In the end, people use adopted English words ("kompjuter" for "computer", "kompajlirati" for "compile," etc.), and if they are unaccustomed to the translated terms may not understand what some pick in a menu is supposed to exercise based on the translated phrase. Therefore, people who understand English, likewise every bit those who are accustomed to English language terminology (who are virtually, because English terminology is also mostly taught in schools because of these problems) regularly cull the original English versions of non-specialist software.
When Cyrillic script is used (for Macedonian and partially Serbian), the problem is similar to other Cyrillic-based scripts.
Newer versions of English Windows permit the lawmaking folio to be changed (older versions crave special English versions with this support), but this setting can be and ofttimes was incorrectly set up. For example, Windows 98 and Windows Me tin can be set to most non-right-to-left single-byte code pages including 1250, simply only at install time.
Caucasian languages [edit]
The writing systems of certain languages of the Caucasus region, including the scripts of Georgian and Armenian, may produce mojibake. This problem is particularly astute in the case of ArmSCII or ARMSCII, a gear up of obsolete grapheme encodings for the Armenian alphabet which accept been superseded by Unicode standards. ArmSCII is not widely used because of a lack of back up in the figurer industry. For instance, Microsoft Windows does non support it.
Asian encodings [edit]
Another type of mojibake occurs when text is erroneously parsed in a multi-byte encoding, such as ane of the encodings for Due east Asian languages. With this kind of mojibake more than ane (typically two) characters are corrupted at one time, due east.g. "k舐lek" ( kärlek ) in Swedish, where " är " is parsed as "舐". Compared to the above mojibake, this is harder to read, since letters unrelated to the problematic å, ä or ö are missing, and is especially problematic for curt words starting with å, ä or ö such as "än" (which becomes "舅"). Since two letters are combined, the mojibake also seems more random (over l variants compared to the normal three, not counting the rarer capitals). In some rare cases, an entire text cord which happens to include a pattern of detail word lengths, such as the judgement "Bush hid the facts", may be misinterpreted.
Vietnamese [edit]
In Vietnamese, the phenomenon is called chữ ma , loạn mã tin occur when computer try to encode diacritic character defined in Windows-1258, TCVN3 or VNI to UTF-8. Chữ ma was common in Vietnam when user was using Windows XP computer or using inexpensive mobile telephone.
| Example: | Trăm năm trong cõi người ta (Truyện Kiều, Nguyễn Du) | |
|---|---|---|
| Original encoding | Target encoding | Effect |
| Windows-1258 | UTF-viii | Trăm due northă1000 trong cõi ngÆ°á»i ta |
| TCVN3 | UTF-8 | Tr¨thousand n¨m trong câi ngêi ta |
| VNI (Windows) | UTF-8 | Traêm naêthousand trong coõi ngöôøi ta |
Japanese [edit]
In Japanese, the same miracle is, as mentioned, chosen mojibake ( 文字化け ). It is a particular trouble in Nippon due to the numerous different encodings that exist for Japanese text. Alongside Unicode encodings like UTF-eight and UTF-16, in that location are other standard encodings, such as Shift-JIS (Windows machines) and EUC-JP (UNIX systems). Mojibake, also every bit being encountered by Japanese users, is also frequently encountered by non-Japanese when attempting to run software written for the Japanese marketplace.
Chinese [edit]
In Chinese, the same miracle is called Luàn mǎ (Pinyin, Simplified Chinese 乱码 , Traditional Chinese 亂碼 , meaning 'chaotic code'), and tin occur when computerised text is encoded in one Chinese character encoding but is displayed using the wrong encoding. When this occurs, it is frequently possible to set up the result by switching the character encoding without loss of information. The situation is complicated considering of the being of several Chinese character encoding systems in use, the nearly mutual ones being: Unicode, Big5, and Guobiao (with several backward compatible versions), and the possibility of Chinese characters being encoded using Japanese encoding.
It is piece of cake to identify the original encoding when luanma occurs in Guobiao encodings:
| Original encoding | Viewed equally | Event | Original text | Note |
|---|---|---|---|---|
| Big5 | GB | ?T瓣в变巨肚 | 三國志曹操傳 | Garbled Chinese characters with no hint of original meaning. The red graphic symbol is not a valid codepoint in GB2312. |
| Shift-JIS | GB | 暥帤壔偗僥僗僩 | 文字化けテスト | Kana is displayed as characters with the radical 亻, while kanji are other characters. Most of them are extremely uncommon and non in practical use in modern Chinese. |

An additional problem is acquired when encodings are missing characters, which is common with rare or antiquated characters that are still used in personal or place names. Examples of this are Taiwanese politicians Wang Chien-shien (Chinese: 王建煊; pinyin: Wáng Jiànxuān )'due south "煊", Yu Shyi-kun (simplified Chinese: 游锡堃; traditional Chinese: 游錫堃; pinyin: Yóu Xíkūn )'s "堃" and singer David Tao (Chinese: 陶喆; pinyin: Táo Zhé )'s "喆" missing in Big5, ex-Prc Premier Zhu Rongji (Chinese: 朱镕基; pinyin: Zhū Róngjī )'s "镕" missing in GB2312, copyright symbol "©" missing in GBK.[9]
Newspapers take dealt with this problem in various ways, including using software to combine two existing, like characters; using a moving-picture show of the personality; or simply substituting a homophone for the rare character in the promise that the reader would be able to make the correct inference.
Indic text [edit]
A similar event can occur in Brahmic or Indic scripts of South asia, used in such Indo-Aryan or Indic languages equally Hindustani (Hindi-Urdu), Bengali, Punjabi, Marä thi, and others, even if the character set employed is properly recognized by the application. This is because, in many Indic scripts, the rules by which private alphabetic character symbols combine to create symbols for syllables may non be properly understood by a computer missing the appropriate software, even if the glyphs for the individual alphabetic character forms are available.
1 example of this is the sometime Wikipedia logo, which attempts to show the character analogous to "wi" (the kickoff syllable of "Wikipedia") on each of many puzzle pieces. The puzzle piece meant to bear the Devanagari character for "wi" instead used to brandish the "wa" character followed by an unpaired "i" modifier vowel, hands recognizable every bit mojibake generated by a figurer not configured to display Indic text.[10] The logo as redesigned as of May 2010[ref] has fixed these errors.
The idea of Plain Text requires the operating system to provide a font to display Unicode codes. This font is different from OS to Bone for Singhala and it makes orthographically incorrect glyphs for some letters (syllables) across all operating systems. For instance, the 'reph', the curt grade for 'r' is a diacritic that normally goes on acme of a plain letter. All the same, it is incorrect to get on top of some letters similar 'ya' or 'la' in specific contexts. For Sanskritic words or names inherited by modern languages, such as कार्य, IAST: kārya, or आर्या, IAST: āryā, information technology is apt to put it on top of these messages. By contrast, for similar sounds in mod languages which issue from their specific rules, it is not put on tiptop, such as the give-and-take करणाऱ्या, IAST: karaṇāryā, a stem class of the common word करणारा/री, IAST: karaṇārā/rī, in the Marāthi language.[11] But it happens in most operating systems. This appears to be a fault of internal programming of the fonts. In Mac OS and iOS, the muurdhaja l (dark l) and 'u' combination and its long class both yield wrong shapes.[ citation needed ]
Some Indic and Indic-derived scripts, virtually notably Lao, were non officially supported by Windows XP until the release of Vista.[12] However, various sites have fabricated free-to-download fonts.
Burmese [edit]
Due to Western sanctions[13] and the late arrival of Burmese language support in computers,[xiv] [fifteen] much of the early Burmese localization was homegrown without international cooperation. The prevailing means of Burmese back up is via the Zawgyi font, a font that was created equally a Unicode font only was in fact only partially Unicode compliant.[15] In the Zawgyi font, some codepoints for Burmese script were implemented as specified in Unicode, but others were not.[16] The Unicode Consortium refers to this as ad hoc font encodings.[17] With the advent of mobile phones, mobile vendors such as Samsung and Huawei simply replaced the Unicode compliant organisation fonts with Zawgyi versions.[xiv]
Due to these ad hoc encodings, communications between users of Zawgyi and Unicode would render equally garbled text. To get around this issue, content producers would make posts in both Zawgyi and Unicode.[18] Myanmar government has designated i October 2019 as "U-Day" to officially switch to Unicode.[13] The full transition is estimated to accept two years.[nineteen]
African languages [edit]
In certain writing systems of Africa, unencoded text is unreadable. Texts that may produce mojibake include those from the Horn of Africa such every bit the Ge'ez script in Ethiopia and Eritrea, used for Amharic, Tigre, and other languages, and the Somali language, which employs the Osmanya alphabet. In Southern Africa, the Mwangwego alphabet is used to write languages of Malawi and the Mandombe alphabet was created for the Congo-kinshasa, but these are not by and large supported. Various other writing systems native to West Africa present like bug, such as the North'Ko alphabet, used for Manding languages in Guinea, and the Vai syllabary, used in Liberia.
Arabic [edit]
Another affected language is Arabic (see below). The text becomes unreadable when the encodings do non lucifer.

The examples in this commodity practice not have UTF-8 as browser setting, because UTF-viii is easily recognisable, so if a browser supports UTF-8 information technology should recognise it automatically, and non attempt to translate something else as UTF-8.
