* Abstract

> This document provides information about character encoding KOI8-U
(KOI8 Ukrainian) wich [INS[原文まま]] 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.

この文書は、ウクライナ語インターネット社会でデファクト標準である文字符号化
KOI8-U (KOI8 ウクライナ語) についての情報を提供します。
KOI8-U は全ての露西亜文字について KOI8-R (RFC 1489) に互換であり、
これを拡張して4つのウクライナ文字について ISO-IR-111 に従った位置に配置しています。
KOI8-U 作業部会の公式サイトは <http://www.net.ua/> です。

* 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.

この文書は、ウクライナ語インターネット社会でウクライナ語のメイルやニュースの交換,
あるいは [[WWW]] 情報[[資源]]の[[表現]]に広く使われている文字符号化
KOI8-U (KOI8 ウクライナ語) についての情報を提供します。

> 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.

元々、提案標準 koi8‐u の仕様は1992年の秋に Kiev の Igor Sviridov
と Kharkiv の Stas Vorony により Slavsk
で行われたウクライナのインターネット・サービス提供者の[RUBYB[投函] [post]]管理者会議で公式に採用されました。1995年6月の終わりに、
この仕様は [CODE(char)[UKRAINIAN GHE WITH UPTURN]]
をもって完成しました。

> 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.

KOI8‐U (KOI8 ウクライナ語) は、多くの[[オペレーティング・システム]]や環境の符号化表、[[フォント]]、[[ロケール]]対応を含む多くのオペレーティング・システムやインターネット利用者応用が対応しています。

> MIME character set name: koi8-u

[[MIME]] [[文字集合]]名: [CODE(charset)[koi8-u]]

* Relation to other RFCs

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

この規格は、幾つかの出版済み規格— [[RFC1489]] (すべての[[露西亜文字]]について完全に互換)、 [[RFC1345]]、 [[ISO-IR-111]]、[[ISO10646]] に基づいています。

* Compatibility with other character sets

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

KOI8‐U ウクライナ五文字集合の下位部分は、 [[KOI8-R]]
や他の非 ASCII [[CodePage]] と同様に、 [[ASCII]]
の完全な複製です。

> The upper part of the KOI8-U Character Set contains all Russian
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.

KOI8‐U 文字集合の上半分は、 KOI8‐R で定義されているすべての露西亜文字と4つのウクライナ文字
([CODE(char)[#164]], [CODE(char)[#180]] — ウクライナ語 [CODE(char)[ie]],
[CODE(char)[#166]], [CODE(char)[#182]] — ウクライナ語 [CODE(char)[i]],
[CODE(char)[#167]], [CODE(char)[#183]] — ウクライナ語 [CODE(char)[yi]],
[CODE(char)[#173]], [CODE(char)[#189]] — ウクライナ語 upturn つき [CODE(char)[ghe]])
を含んでいます。
ウクライナ文字の位置は ISO-IR-111 に従っています。

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

他の (ウクライナ文字が使っていない) 位置の[[罫線素片]]は KOI8‐R
文字集合と同じです。 KOI8‐R と提案する KOI8‐U
の間のすべての差異の一覧は附属書 A にあります。

* Specification of the upper part of KOI8-U codepage

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

KOI8‐U 符号頁の上位半分のすべての文字の説明は ISO 10646 [[Unicode]]
文字集合 ([[UCS]]) に従って与えます。

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

RFC 1345 書式の KOI8‐U charset 表は附属書 B に与えます。
