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. ;;; Code: ;; Cyrillic (general) ;; ISO-8859-5 stuff (define-coding-system 'cyrillic-iso-8bit "ISO 2022 based 8-bit encoding for Cyrillic script (MIME:ISO-8859-5)." :coding-type 'charset :mnemonic ?5 :charset-list '(iso-8859-5) :mime-charset 'iso-8859-5) (define-coding-system-alias 'iso-8859-5 'cyrillic-iso-8bit) (set-language-info-alist "Cyrillic-ISO" '((charset iso-8859-5) (coding-system cyrillic-iso-8bit) (coding-priority cyrillic-iso-8bit) (input-method .
