Character sets

ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable and 33 control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII.

KOI-8 (КОИ-8) is an 8-bit character set standardized in GOST 19768-74. 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 additio

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 st

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.

ArmSCII is an acronym for Armenian Standard Code for Information Interchange, similar to ASCII for the American standard. It has been superseded by the Unicode standard.

YUSCII is an informal name for several JUS standards for 7-bit character encoding. These include: JUS I.B1.002 (ISO-IR-141, ISO 646-YU), which encodes Gaj's Latin alphabet, used for Serbo-Croatian and Slovenian language JUS I.B1.003 (ISO-IR-146), which encodes Serbian Cyrillic alphabet, and JUS I.B1.004 (ISO-IR-147), which encodes Macedonian Cyrillic alphabet.

VISCII is an unofficially defined modified ASCII character encoding for using the Vietnamese language with computers. It should not be confused with the similarly named officially registered VSCII encoding. VISCII keeps the 95 printable characters of ASCII unmodified, but it replaces 6 of the 33 control characters with printable characters. It adds 128 precomposed characters. Unicode and the Windows-1258 code page are now used for virtually all Vietnamese computer data, but legacy VSCII and VISCII files may need conversion.

(), also known by its full name , is a character encoding scheme created to provide a complete index of characters used in the Chinese, Japanese, Korean, Vietnamese Chữ Nôm and other historical Chinese logographic writing systems. The , which published the character set, also published computer software and TrueType computer fonts to accompany it. The Mojikyō Institute, chaired by , originally had its character set and related software and data redistributed on CD-ROMs sold in Kinokuniya stores.
