Windows-1251
Windows-1251 is an 8-bit character encoding, designed to cover languages that use the Cyrillic script such as Russian, Ukrainian, Belarusian, Bulgarian, Serbian Cyrillic, Macedonian and other languages. On the web, it is the second most-used single-byte character encoding (or third most-used character encoding overall), and most used of the single-byte encodings supporting Cyrillic. , 0.3% of all websites use Windows-1251. It's by far mostly used for Russian, while a small minority of Russian websites use it, with 94.6% of Russian (.ru) websites using UTF-8, and the legacy 8-bit encoding is distant second. In Linux, the encoding is known as cp1251. IBM uses code page 1251 ( CCSID 1251 and euro sign extended CCSID 5347) for Windows-1251. Windows-1251 and KOI8-R (or its Ukrainian variant KOI8-U) are much more commonly used than ISO 8859-5 (which is used by less than 0.0004% of websites). In contrast to Windows-1252 and ISO 8859-1, Windows-1251 is not closely related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO-IR-111
ISO-IR-111 or KOI8-E is an 8-bit character set. It is a multinational extension of KOI-8 for Belarusian, Macedonian, Serbian, and Ukrainian (except Ґґ which is added to KOI8-F). The name "ISO-IR-111" refers to its registration number in the ISO-IR registry, and denotes it as a set usable with ISO/IEC 2022. It was defined by the first (1986) edition of ECMA-113, which is the Ecma International standard corresponding to , and as such also corresponds to a 1987 draft version of ISO-8859-5. The published editions of instead correspond to subsequent editions of ECMA-113, which defines a different encoding. Naming confusion ISO-IR-111, the 1985 edition of ECMA-113 (also called "ECMA-Cyrillic" or "KOI8-E"), was based on the 1974 edition of GOST 19768 (i.e. KOI-8). In 1987 ECMA-113 was redesigned. These newer editions of ECMA-113 are equivalent to ISO-8859-5, and do not follow the KOI layout. This confusion has led to a common misconception that ISO-8859-5 was defined in or ...

ISO 8859-5
ISO/IEC 8859-5:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 5: Latin/Cyrillic alphabet'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1988. It is informally referred to as Latin/Cyrillic. It was designed to cover languages using a Cyrillic alphabet such as Bulgarian, Belarusian, Russian, Serbian and Macedonian but was never widely used. The 8-bit encodings KOI8-R and KOI8-U, IBM-866, and also Windows-1251 are far more commonly used. In contrast to the relationship between Windows-1252 and ISO 8859-1, Windows-1251 is not closely related to ISO 8859-5. However, the main Cyrillic block in Unicode uses a layout based on ISO-8859-5. ISO 8859-5 would also have been usable for Ukrainian in the Soviet Union from 1933 to 1990, but it is missing the Ukrainian letter ''ge'', ґ, which is required in Ukrainian orthography before and since, and during that perio ...

KOI8-U
KOI8-U (RFC 2319) is an 8-bit character encoding, designed to cover Ukrainian, which uses a Cyrillic alphabet. It is based on KOI8-R, which covers Russian and Bulgarian, but replaces eight box drawing characters with four Ukrainian letters Ґ, Є, І, and Ї in both upper case and lower case. KOI8-RU is closely related, but adds Ў for Belarusian. In both, the letter allocations match those in KOI8-E, except for Ґ which is added to KOI8-F. In Microsoft Windows, KOI8-U is assigned the code page number 21866. In IBM, KOI8-U is assigned code page/ CCSID 1168. KOI8 remains much more commonly used than ISO 8859-5, which never really caught on. Another common Cyrillic character encoding is Windows-1251. In the future, both may eventually give way to Unicode. KOI8 stands for ''Kod Obmena Informatsiey, 8 bit'' () which means "Code for Information Exchange, 8 bit". The KOI8 character sets have the property that the Cyrillic letters are in pseudo-Latin alphabetic order rath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KOI8-R
KOI8-R (RFC 1489) is an 8-bit character encoding derived from the KOI-8 encoding by the programmer Andrei Chernov in 1993 and designed to cover Russian, which uses the Russian subset of a Cyrillic script. KOI-8, on its turn, is an 8-bit extension of the KOI-7 encoding, which inherited a phonetic correspondence of Russian and Latin letters from the MTK-2 teletype code. As a result, Russian Cyrillic letters in KOI8-R are in pseudo-Latin alphabetical order rather than the normal Cyrillic one like in ISO 8859-5. Although this may seem unnatural, this has the useful effect that if the 8th bit is stripped, the text remains partially readable in any ASCII-based encoding (including KOI8-R itself) as a case-reversed transliteration. For example, "Код для обмена и обработки информации" (the Russian meaning of the "KOI" acronym) becomes ''kOD DLQ OBMENA I OBRABOTKI INFORMACII''. KOI-8 stands for ''8-bitnyy kod dlya obmena i obrabotki informatsii'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows-125x
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used. Current Windows versions support Unicode, new Windows applications should use Unicode (UTF-8) and not 8-bit character encodings. There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages. (ANSI is the American National Standards Institute.) Code pages in both of these groups are extended ASCII code pages. Additional code pages are supported by standard Windows conversion routines, but not used as either type of system code page. ANSI code page ANSI code pages (officially called "Windows code pages" after Microsoft accepted the former term being a misnomer) ...

EUC-KR
Extended Unix Code (EUC) is a multibyte character encoding system used primarily for Japanese language, Japanese, Korean language, Korean, and simplified Chinese characters, simplified Chinese (characters). The most commonly used EUC codes are variable-width encoding, variable-length encodings with a character belonging to an compliant coded character set (such as ASCII) taking one byte, and a character belonging to a 94×94 coded character set (such as ) represented in two bytes. The EUC-CN form of and EUC-KR are examples of such two-byte EUC codes. EUC-JP includes characters represented by up to three bytes, including an initial , whereas a single character in EUC-TW can take up to four bytes. Modern applications are more likely to use UTF-8, which supports all of the glyphs of the EUC codes, and more, and is generally more portable with fewer vendor deviations and errors. EUC is however still very popular, especially EUC-KR for South Korea. Encoding structure The structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrillic Script
The Cyrillic script ( ) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic languages, Slavic, Turkic languages, Turkic, Mongolic languages, Mongolic, Uralic languages, Uralic, Caucasian languages, Caucasian and Iranian languages, Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages. , around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the Languages of the European Union#Writing systems, European Union, following the Latin script, Latin and Greek alphabet, Greek alphabets. The Early Cyrillic alphabet was developed during the 9th century AD at the Preslav Literary School in the First Bulga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Character Encoding
Character encoding is the process of assigning numbers to graphical character (computing), characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers. The numerical values that make up a character encoding are known as code points and collectively comprise a code space or a code page. Early character encodings that originated with optical or electrical telegraphy and in early computers could only represent a subset of the characters used in written languages, sometimes restricted to Letter case, upper case letters, Numeral system, numerals and some punctuation only. Over time, character encodings capable of representing more characters were created, such as ASCII, the ISO/IEC 8859 encodings, various computer vendor encodings, and Unicode encodings such as UTF-8 and UTF-16. The Popularity of text encodings, most popular character encoding on the World Wide Web is UTF-8, which is used in 98.2% of surve ...

Code Page
In computing, a code page is a character encoding and as such it is a specific association of a set of printable character (computing), characters and control characters with unique numbers. Typically each number represents the binary value in a single byte. (In some contexts these terms are used more precisely; see .) The term "code page" originated from IBM's EBCDIC-based mainframe systems, but Microsoft, SAP AG, SAP, and Oracle Corporation are among the vendors that use this term. The majority of vendors identify their own character sets by a name. In the case when there is a plethora of character sets (like in IBM), identifying character sets through a number is a convenient way to distinguish them. Originally, the code page numbers referred to the page number, ''page'' numbers in the IBM standard character set manual, a condition which has not held for a long time. Vendors that use a code page system allocate their own code page number to a character encoding, even if it is be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

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. , 1.1% of all web sites use . It is the most declared single-byte character encoding, but as Web browsers and the HTML5 standard interpret them as the superset Windows-1252, these documents may include characters from that set. Some countries or languages show a higher usage than the global average, in 2025 Brazil according to website use, use is at 2.9%, and in Germany at 2.3%. ISO-8859-1 was ...

Windows-1252
Windows-1252 or CP-1252 ( Windows code page 1252) is a legacy single-byte character encoding that is used by default (as the "ANSI code page") in Microsoft Windows throughout the Americas, Western Europe, Oceania, and much of Africa. Initially the same as ISO 8859-1, it began to diverge starting in Windows 2.0 by adding additional characters in the 0x80 to 0x9F ( hex) range (the ISO standards reserve this range for C1 control codes). Notable additional characters include curly quotation marks and all printable characters from ISO 8859-15. It is the most-used single-byte character encoding in the world. Although almost all websites now use the multi-byte character encoding UTF-8, , 1.1% of websites declared ISO 8859-1 which is treated as Windows-1252 by all modern browsers (as required by the HTML5 standard), plus 0.3% declared Windows-1252 directly, for a total of 1.4%.
