Mojibake
Mojibake ( ja, 文字化け; , "character transformation") is the garbled text that is the result of text being decoded using an unintended character encoding. 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, as 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 8-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 be confused with mojibake. Symptoms of this failed rendering include blocks with the code point displayed in h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specials (Unicode Block)
Specials is a short Unicode block of characters allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 code points, five have been assigned since Unicode 3.0: *, marks start of annotated text *, marks start of annotating character(s) *, marks end of annotation block *, placeholder in the text for another unspecified object, for example in a compound document. * used to replace an unknown, unrecognized, or unrepresentable character * not a character. * not a character. FFFE and FFFF are not unassigned in the usual sense, but guaranteed not to be Unicode characters at all. They can be used to guess a text's encoding scheme, since any text containing these is by definition not a correctly encoded Unicode text. Unicode's character can be inserted at the beginning of a Unicode text to signal its endianness: a program reading such a text and encountering 0xFFFE would then know that it should switch the byte order for all the following characters. ...

Charset Detection
Character encoding detection, charset detection, or code page detection is the process of heuristically guessing the character encoding of a series of bytes that represent text. The technique is recognised to be unreliable and is only used when specific metadata, such as a HTTP header is either not available, or is assumed to be untrustworthy. This algorithm usually involves statistical analysis of byte patterns, like frequency distribution of trigraphs of various languages encoded in each code page that will be detected; such statistical analysis can also be used to perform language detection. This process is not foolproof because it depends on statistical data. In general, incorrect charset detection leads to mojibake. One of the few cases where charset detection works reliably is detecting UTF-8. This is due to the large percentage of invalid byte sequences in UTF-8, so that text in any other encoding that uses bytes with the high bit set is ''extremely'' unlikely to pass ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with ISO/IEC 10646, each being code-for-code identical with the other. ''The Unicode Standard'', however, includes more than just the base code.

Windows-31J
Microsoft Windows code page 932 (abbreviated MS932, Windows-932 or ambiguously CP932), also called Windows-31J amongst other names (see § Terminology below), is the Microsoft Windows code page for the Japanese language, which is an extended variant of the Shift JIS Japanese character encoding. It contains standard 7-bit ASCII codes, and Japanese characters are indicated by the high bit of the first byte being set to 1. Some code points in this page require a second byte, so characters use either 8 or 16 bits for encoding. IBM offer the same extended double-byte codes in their code page 943 (IBM-943 or CP943), which is a combination of the single-byte Code page 897 and the double-byte Code page 941. Windows-31J is the most used non-UTF-8/Unicode Japanese encoding on the web. Actually is the much more declared encoding, but by W3C/WHATWG HTML standards, the encodings are declared the same, and while the latter name is used in the standards it's defined to decode the former ...

Text File
A text file (sometimes spelled textfile; an old alternative name is flatfile) is a kind of computer file that is structured as a sequence of lines of electronic text. A text file exists stored as data within a computer file system. In operating systems such as CP/M and MS-DOS, where the operating system does not keep track of the file size in bytes, the end of a text file is denoted by placing one or more special characters, known as an end-of-file marker, as padding after the last line in a text file. On modern operating systems such as Microsoft Windows and Unix-like systems, text files do not contain any special EOF character, because file systems on those operating systems keep track of the file size in bytes. Most text files need to have end-of-line delimiters, which are done in a few different ways depending on operating system. Some operating systems with record-orientated file systems may not use new line delimiters and will primarily store text files with lines se ...

Windows-1252
Windows-1252 or CP-1252 ( code page 1252) is a single-byte character encoding of the Latin alphabet, used by default in the legacy components of Microsoft Windows for English and many European languages including Spanish, French, and German. It is the most-used single-byte character encoding in the world (on websites at least). , 0.3% of all websites declared use of Windows-1252, but at the same time 1.3% used ISO 8859-1 (while only 8 of the top 1000 websites), which by HTML5 standards should be considered the same encoding, so that 1.6% of websites effectively use Windows-1252. Pages declared as US-ASCII would also count as this character set. An unknown (but probably large) subset of other pages use only the ASCII portion of UTF-8, or only the codes matching Windows-1252 from their declared character set, and could also be counted. Depending on the country, use can be much higher than the global average, e.g., for Brazil according to website use (including ISO-8859-1), ...

ISO-8859-1
ISO/IEC 8859-1:1998, ''Information technology — 8-bit single-byte coded graphic character sets — Part 1: Latin alphabet No. 1'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. ISO/IEC 8859-1 encodes what it refers to as "Latin alphabet no. 1", consisting of 191 characters from the Latin script. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is the basis for some popular 8-bit character sets and the first two blocks of characters in Unicode. ISO-8859-1 was (according to the standard, at least) the default encoding of documents delivered via HTTP with a MIME type beginning with "text/" ( HTML5 changed this to Windows-1252). , 1.3% of all (but only 8 of the top 1000) web sites use . It is the most ''declared'' single-byte character encoding in the world on the Web, but as Web browsers interpret it as the superset Windows-1252, the documen ...

GBK (character Encoding)
GBK is an extension of the GB 2312 character set for Simplified Chinese characters, used in the People's Republic of China. It includes all unified CJK characters found in , i.e. ISO/IEC 10646:1993, or Unicode 1.1. Since its initial release in 1993, GBK has been extended by Microsoft in Code page 936/1386, which was then extended into GBK 1.0. GBK is also the IANA-registered internet name for the Microsoft mapping, which differs from other implementations primarily by the single-byte euro sign at 0x80. ''GB'' abbreviates Guojia Biaozhun, which means ''national standard'' in Chinese, while ''K'' stands for ''Extension'' (扩展 ''kuòzhǎn''). GBK not only extended the old standard with Traditional Chinese characters, but also with Chinese characters that were simplified after the establishment of in 1981. With the arrival of GBK, certain names with characters formerly unrepresentable, like the 镕 (''róng'') character in former Chinese Premier Zhu Rongji's name, are n ...

Locale (computer Software)
In computing, a locale is a set of parameters that defines the user's language, region and any special variant preferences that the user wants to see in their user interface. Usually a locale identifier consists of at least a language code and a country/region code. Locale is an important aspect of i18n. General locale settings These settings usually include the following display (output) format settings: * Number format setting * Character classification, case conversion settings * Date-time format setting * String collation setting * Currency format setting * Paper size setting * Color setting The locale settings are about formatting output given a locale. So, the time zone information and daylight saving time are not usually part of the locale settings. Less usual is the input format setting, which is mostly defined on a per application basis. Programming and markup language support In these environments, * C * C++ * Eiffel * Java * .NET Framework * REBOL * Ruby * P ...

Byte Order Mark
The byte order mark (BOM) is a particular usage of the special Unicode character, , whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: * The byte order, or endianness, of the text stream in the cases of 16-bit and 32-bit encodings; * The fact that the text stream's encoding is Unicode, to a high level of confidence; * Which Unicode character encoding is used. BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream. Unicode can be encoded in units of 8-bit, 16-bit, or 32-bit integers. For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. The BOM is encoded in the same scheme as the rest of the document and becomes a Unicode code point if its bytes are swapped. Hence, the process acce ...
