KOI8-B
KOI8-B is the informal name for an 8-bit Roman / Cyrillic character set constituting the common subset of the major KOI-8 variants (KOI8-R, KOI8-U, KOI8-RU, KOI8-E, KOI8-F). Accordingly, it is closely related to KOI8-R, but defines only the letter subset in the upper half. As such it was implemented by some font vendors for PC Unixes like Xenix in the late 1980s. Character set The following table shows the KOI8-B encoding. Each character is shown with its equivalent Unicode code point.

KOI8-T
KOI8-T is an 8-bit single-byte extended ASCII character encoding adapting KOI8 to cover the Tajik Cyrillic alphabet. It was introduced by Michael Davis as an interim solution for representing Tajiki Cyrillic text in an interchangeable manner appropriate for use on the web, in an attempt to bridge the gap between existing non-interoperable font-specific encodings and the eventual wide adoption of Unicode. It is used by the GNU C Library as its default encoding for Tajik. The Cyrillic letters that are also used in Russian are encoded according to the KOI8-R layout, making the encoding a KOI8-B superset, whereas the punctuation mostly follows the layout in Windows-1251 and 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. ... as applicable.

KOI-8
KOI-8 (КОИ-8) is an 8-bit character set standardized in GOST 19768-74. Маркелова Л. Н. Эксплуатация программоуправляемой вычислительной машины «Искра 226». — М.: Машиностроение, 1987. — С. 41—42. It is an extension of KOI-7 which allows the use of the Latin alphabet along with the Russian alphabet, both the upper and lower case letters; however, the letter Ёё and the uppercase Ъ are missed, the latter to avoid conflicts with the delete character (both are added in most extensions, see KOI8-B). The first 127 code points are identical to ASCII with the exception of the dollar sign $ (code point 24hex) replaced by the universal currency sign ¤. The rows x8_ and x9_ (code points 128–159) might be filled with the additional control characters from EBCDIC (code points 32–63). This standard has become the base for the later Internet standards such as KOI8-R, KOI8-U, KOI8-RU and a ... [...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 a Cyrillic alphabet. KOI8-R was based on Russian Morse code, which was created from a phonetic version of Latin Morse code. As a result, Russian Cyrillic letters are in pseudo-Roman order rather than the normal Cyrillic alphabetical order. Although this may seem unnatural, if the 8th bit is stripped, the text is partially readable in ASCII and may convert to syntactically correct KOI-7. For example, "Русский Текст" in KOI8-R becomes ''rUSSKIJ tEKST'' ("Russian Text"). KOI8 stands for ''Kod Obmena Informatsiey, 8 bit'' (russian: Код Обмена Информацией, 8 бит) which means "Code for Information Exchange, 8 bit". In Microsoft Windows, KOI8-R is assigned the code page number 20866. In IBM, KOI8-R is assigned code page 878. KOI8-R also happens to cover Bulgarian, but has not been use ...

KOI Character Encodings
KOI (''КОИ'') is a family of several code pages for the Cyrillic script. The name stands for ''Kod obmena informatsiey'' (russian: Код обмена информацией) which means "Code for Information Interchange". A particular feature of the KOI code pages is that the text remains human-readable when the leftmost bit is stripped, should it inadvertently pass through equipment or software that can only deal with 7 bit wide characters. This is due to characters being placed in a special order (128 codepoints apart from the Latin letter they sound most similar to), which, however, does not correspond to the alphabetic order in any language that is written in Cyrillic and necessitates the use of lookup tables to perform sorting. These encodings are derived from ASCII on the base of some correspondence between Latin and Cyrillic (nearly phonetical), which was already used in Russian dialect of Morse code and in MTK-2 telegraph code. The first 26 characters from А (0xE1) in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KOI8-U
KOI8-U (RFC 2319) is an 8-bit character encoding, designed to cover Ukrainian language, Ukrainian, which uses a Cyrillic alphabet. It is based on KOI8-R, which covers Russian language, Russian and Bulgarian language, Bulgarian, but replaces eight box drawing characters with four Ukrainian letters Ghe with upturn, Ґ, Ukrainian Ye, Є, Soft-dotted i (Cyrillic), І, and Yi (Cyrillic), Ї in both upper case and lower case. KOI8-RU is closely related, but adds Ў for Belarusian language, 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-RU
KOI8-RU is an 8-bit character encoding, designed to cover Russian, Ukrainian, and Belarusian which use a Cyrillic alphabet. It is closely related to KOI8-R, which covers Russian and Bulgarian, but replaces ten box drawing characters with five Ukrainian and Belarusian letters Ґ, Є, І, Ї, and Ў in both upper case and lower case. It is even more closely related to KOI8-U, which does not include Ў but otherwise makes the same replacements. The additional letter allocations are matched by KOI8-E, except for Ґ which is added to KOI8-F. In IBM, KOI8-RU is assigned code page/CCSID 1167. 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-E
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 based ...

KOI8-F
KOI8-F or KOI8 Unified is an 8-bit character set. It was designed by Peter Cassetta of Fingertip Software (now defunct) as an attempt to support all the encoded letters from both KOI8-E (ISO-IR-111) and KOI8-RU (and hence also, KOI8-U and KOI8-R), along with some of the pseudographics from KOI8-R, with some additional punctuation in the remaining space, sourced partly from Windows-1251. This encoding was only used in the software of that company. Character set The following table shows the KOI8-F encoding. Each character is shown with its equivalent Unicode code point. Differences from ISO-IR-111 are boxed; other relevant encodings which are matched, if any, are noted in footnotes.

ISO-IR-153
ISO-IR-153 (ST SEV 358-88) is an 8-bit character set that covers the Russian and Bulgarian alphabets. Unlike the KOI encodings, this encoding lists the Cyrillic letters in their correct traditional order. This has become the basis for ISO/IEC 8859-5 and the Cyrillic Unicode block. Standards and Naming The name ISO-IR-153 refers to this set's number in the ISO-IR registry, and marks it as a set which may be used within ISO/IEC 2022. ISO-IR-153 is a subset of ISO/IEC 8859-5 (synchronised with ECMA-113 since 1988). The ISO-IR-153 documentation cites ST SEV 358-88 as the source standard. While it also cites the earlier GOST 19768-74 (which defines KOI-8 and was conformed to by the first version of ECMA-113, i.e. ISO-IR-111), it does not follow the KOI-8 layout (rather using a close modification of the letter layout from the Main code page) so this appears to be in error. The ISO-IR-153 encoding was intended to replace GOST 19768-74, and is sometimes referred to as GOST-19768-87. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comma (punctuation)
The comma is a punctuation mark that appears in several variants in different languages. It has the same shape as an apostrophe or single closing quotation mark () in many typefaces, but it differs from them in being placed on the baseline of the text. Some typefaces render it as a small line, slightly curved or straight, but inclined from the vertical. Other fonts give it the appearance of a miniature filled-in figure on the baseline. The comma is used in many contexts and languages, mainly to separate parts of a sentence such as clauses, and items in lists mainly when there are three or more items listed. The word ''comma'' comes from the Greek (), which originally meant a cut-off piece, specifically in grammar, a short clause. A comma-shaped mark is used as a diacritic in several writing systems and is considered distinct from the cedilla. In Byzantine and modern copies of Ancient Greek, the " rough" and "smooth breathings" () appear above the letter. In Latvian, R ...

Bracket
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterisk
The asterisk ( ), from Late Latin , from Ancient Greek , ''asteriskos'', "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). In English, an asterisk is usually five- or six-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication. History The asterisk has already been used as a symbol in ice age cave paintings. There is also a two thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen is know ...
