 .SH DESCRIPTION
-KOI8-R is the character set of choice for encoding Russian texts for
-many UNIX-like operation systems.
-KOI8-R is a successor for KOI-8, a
-de-facto standard for Internet Mail, News, WWW, and other interactive
-services at least all over the ex-SU territory.

-KOI8-R is defined by RFC\ 1489 (Registration of a Cyrillic Character
-Set).
-.SH NOTES
-KOI8-R was designed for mixed Russian/English texts and covers
-only Russian Cyrillic characters,
-so if you're looking for Cyrillic characters for Ukrainian,
-Byelorussian, and so on,
-try ISO-IR-111, or KOI8-U
-(Ukrainian Character Set), or KOI8-C (for ancient Russian texts)
-instead, which are identical to KOI8-R in the Russian Cyrillic letters
-area.
-.PP
-A more complete set of Cyrillic characters is also defined by the
-ISO-8859-5 character set.
+RFC\ 1489 defines an 8-bit character set, KOI8-R. 
+KOI8-R encodes the
+characters used in Russian.
