;;; Commentary:
|
||
|
||
;; The character set ISO8859-5 is supported. KOI-8 and ALTERNATIVNYJ
|
||
;; are converted to Unicode internally. See
|
||
;; <URL:http://www.ecma.ch/ecma1/STAND/ECMA-113.HTM>. For more info
|
||
;; on Cyrillic charsets, see
|
||
;; <URL:http://czyborra.com/charsets/cyrillic.html>. The KOI and
|
||
;; Alternativnyj coding systems should live in code-pages.el, but
|
||
;; they've always been preloaded and the coding system autoload
|
||
;; mechanism didn't get accepted, so they have to stay here and
|
||
;; duplicate code-pages stuff.
|
||
|
||
;; Note that 8859-5 maps directly onto the Unicode Cyrillic block,
|
||
;; apart from codepoints 160 (NBSP, c.f. U+0400), 173 (soft hyphen,
|
||
;; c.f. U+04OD) and 253 (section sign, c.f U+045D). The KOI-8 and
|
||
;; Alternativnyj coding systems encode both 8859-5 and Unicode.
|
||
;; ucs-tables.el provides unification for cyrillic-iso-8bit.
|
||
|
||
;; Customizing `utf-fragment-on-decoding' allows decoding characters
|
||
;; from KOI and Alternativnyj into 8859-5 where that's possible.
|
||
;; cyrillic-iso8859-5 characters take half as much space in the buffer
|
||
;; as the mule-unicode-0100-24ff equivalents, though that's probably
|
||
;; not normally a big deal.
