This document provides information about character encoding KOI8-
(KOI8 Ukrainian) wich is a de-facto standard in Ukrainian
community. KOI8-U is compatible with KOI8-R (RFC 1489) in
Russian letters and extends it with four Ukrainian letters
locations are compliant with ISO-IR-111. The official site of KOI8-
Working Group is http://www.net.ua

This document provides information about character encoding KOI8-
(KOI8 Ukrainian) widely used in Ukrainian Internet community for
and news exchange as well as for presentation of WWW
resources in Ukrainian language

Originally, specification of proposed standard koi8-u was
adopted by the conference of Postmasters of Ukrainian
Service Providers in Slavsk in Autumn of 1992 presented by
Sviridov from Kiev and Stas Vorony from Kharkiv. Later in June 1995
this specification was completed with UKRAINIAN GHE WITH UPTURN

KOI8-U (KOI8 Ukrainian) is a de-facto standard supported in
operation systems and Internet user applications including
tables, fonts, locale support for many operating systems
environments

MIME character set name: koi8-

RFC 2319 Ukrainian Character Set KOI8-U April 1998

Relation to other

This standard is based on several published standards: RFC1489 (
is fully compatible in all Russian letters), RFC-1345, ISO-IR-111,
ISO 10646.

Compatibility with other character

The lower part of the KOI8-U Ukrainian Character Set is a
copy of ASCII, just as it's used in KOI8-R and other non-
codepages

The upper part of the KOI8-U Character Set contains all
letters defined in KOI8-R and four Ukrainian letters (#164, #180 -
ukr. ie, #166, #182 - ukr. i, #167, #183 - ukr. yi, #173, #189 - ukr
ghe with upturn) which locations are compliant with ISO-IR-111.

BOX DRAWINGS elements in the other positions (that are not used
Ukrainian letters) are the same as in KOI8-R character set. List
all differences between KOI8-R and proposed KOI8-U is given
APPENDIX A

Specification of the upper part of KOI8-U

The description of all characters of upper half part of KOI8-
codepage is given according to ISO 10646 Unicode Character Set (UCS).

KOI8-U charset table in RFC1345 format is given in Appendix B

if you see any problems within the linking, don't worry be happy,
this is version 0.1 of the Relevance System and you gotta expect some crappy subroutines sometimes,
just be content we did not write this in Java, which would have made this "bigger and better" HAHAHHA.
