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   Published specification: This standard is unpublished, but based on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