Network Working Group KOI8-U Working Group Request for Comments: 2319 April 1998 Category: Informational Ukrainian Character Set KOI8-U Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (1998). All Rights Reserved. Abstract This document provides information about character encoding KOI8-U (KOI8 Ukrainian) wich is a de-facto standard in Ukrainian Internet community. KOI8-U is compatible with KOI8-R (RFC 1489) in all Russian letters and extends it with four Ukrainian letters which locations are compliant with ISO-IR-111. The official site of KOI8-U Working Group is http://www.net.ua. Introduction This document provides information about character encoding KOI8-U (KOI8 Ukrainian) widely used in Ukrainian Internet community for mail and news exchange as well as for presentation of WWW information resources in Ukrainian language. Originally, specification of proposed standard koi8-u was officially adopted by the conference of Postmasters of Ukrainian Internet Service Providers in Slavsk in Autumn of 1992 presented by Igor 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 many operation systems and Internet user applications including encoding tables, fonts, locale support for many operating systems and environments.
