Abstract

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. This memo provides information for the Internet community. It does not specify an Internet standard.

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Published specification: This standard is unpublished, but based on several published standards: GOST 19768-74 (old-koi8), ISO 6937/8 (not registered) and variations: INIS-cyrillic, ISO 5427.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,
