               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  Published specification: This standard is unpublished, but based on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] = {
