Letters and completes it with four Ukrainian letters which
locations are complaint with ISO-IR-111.

Introduction
This document provides information about widely
used in Ukrainian Internet community character set for mail and news
exchange as well as for presentation WWW information resources in
Ukrainian language.
Though the proposed character set "KOI8-RU" is not currently an
international standard, there is large Internet user community
Expires in six months [Page 1]
Internet Draft Ukrainian Cyrillic Charset KOI8-RU October 1997
(including Ukraine and worldwide Ukrainian speaking community)
supporting it.
"KOI8-RU" (KOI8 Russian and Ukrainian) summarises and completes
de-facto standard koi8-u accepted by all Ukrainian community in the
Internet and unofficially published at many sites
(F.E., ftp://ftp.ua.net/pub/info/encodings/koi8-u/ukr_chars_in_koi8-
u_and_others.txt; ftp://ftp.gu.kiev.ua/pub/koi8-u/ukr_chars_in_koi8-
u_and_others.txt; http://cad.ntu-kpi.kiev.ua/multiling/KOI8-U.html).
Ukrainian language is the 20th among the world's languages (http://
www.isoc.org:8080/langues/iso639.htm) and supported not only in
Ukraine as national state but among Ukrainian communities over the
world.
KOI8-RU should be registered to support and facilitate general and
cultural information content development and dissemination. Support
of Ukrainian language in new software product is restrained by absent
of officially registered and widely published de-facto used Ukrainian
charset.
One of the problem now is that all old codepages ISO-IR-111, ISO
8859-5 doesn't include new Ukr. letter GHE (with upturn). Now it's
registered in UNICODE 2.0.14 as Cyrillic GHE with upturn (0490 -
capital, 0491 - small). It is used in more than 25 ukrainian words
and carry in some cases specific national features.
Compatibility with other character sets
This standard is unpublished but based on several published
standards: first of all, RFC1489 (it is fully complaint in all
russian letters), ISO 8859-5, ISO-IR-111, UNICODE 2.0.14.
KOI8-RU is compatible with KOI8-R in all Cyrillic Letters and
completes it with four Ukrainian (#164, #180 - ukr. ie, #166, #182 -
ukr. i, #167, #183 - ukr. yi, #173, #189 - ukr. ghe with upturn) and
one Byelorussian (#174, #190 - byelorussian short u) letters which
locations are complaint with ISO-IR-111.
All FORMS except positions occupied by Ukrainian and Byelorussian
letters and Bullets in positions #148, #149, #158 coincide with
KOI8-R.
Positions #147, #150-153, #155-#157, #159 are used for important
characters which are currently missing from ISO-IR-111.
