RFC 1489 Network Working Group A. Chernov Request for Comments: 1489 RELCOM Development Team July 1993 Registration of a Cyrillic Character Set Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. Introduction Though the proposed character set "koi8-r" is not currently an international standard, there is very large user community (including Relcom Net) supporting it. Factually, "koi8-r" is de-facto standard for Unix and global network applications in the former Soviet Union. This is the reason the Society of Unix User Groups (SUUG) believes "koi8-r" should be registered. MIME character set name: koi8-r Published specification: This standard is unpublished, but based on several published standards: GOST 19768-74 (old-koi8), ISO 6937/8 (not registered) and variations: INIS-cyrillic, ISO 5427. C language coding table from koi8-r to Unicode (ISO 10646) for the upper half of the code table (the lower half of the table is fully coinciding with ASCII character set) unsigned short koi82unicode[128] = { 0x2500,0x2502,0x250c,0x2510,0x2514,0x2518,0x251c,0x2524, 0x252c,0x2534,0x253c,0x2580,0x2584,0x2588,0x258c,0x2590, 0x2591,0x2592,0x2593,0x2320,0x25a0,0x2219,0x221a,0x2248, 0x2264,0x2265,0x00a0,0x2321,0x00b0,0x00b2,0x00b7,0x00f7, 0x2550,0x2551,0x2552,0x0451,0x2553,0x2554,0x2555,0x2556, 0x2557,0x2558,0x2559,0x255a,0x255b,0x255c,0x255d,0x255e, 0x255f,0x2560,0x2561,0x0401,0x2562,0x2563,0x2564,0x2565, 0x2566,0x2567,0x2568,0x2569,0x256a,0x256b,0x256c,0x00a9, 0x044e,0x0430,0x0431,0x0446,0x0434,0x0435,0x0444,0x0433, 0x0445,0x0438,0x0439,0x043a,0x043b,0x043c,0x043d,0x043e, 0x043f,0x044f,0x0440,0x0441,0x0442,0x0443,0x0436,0x0432, 0x044c,0x044b,0x0437,0x0448,0x044d,0x0449,0x0447,0x044a, 0x042e,0x0410,0x0411,0x0426,0x0414,0x0415,0x0424,0x0413, 0x0425,0x0418,0x0419,0x041a,0x041b,0x041c,0x041d,0x041e, 0x041f,0x042f,0x0420,0x0421,0x0422,0x0423,0x0416,0x0412, Chernov [Page 1] RFC 1489 Registration of a Cyrillic Character Set July 1993 0x042c,0x042b,0x0417,0x0428,0x042d,0x0429,0x0427,0x042a };
