Subject: codepage.el: Codepage Mapping, Latin-7
Date: Thu, 16 Mar 2006 15:35:57 +0100 [thread overview]
Message-ID: <v91wx2v4mq.fsf@marauder.physik.uni-ulm.de> (raw)
Hi,
from lisp/international/codepage.el:
--8<---------------cut here---------------start------------->8---
;; Support for the Windows 12xx series of codepages that MS has
;; butchered from the ISO-8859 specs. This does not add support for
;; the extended characters that MS has added in the 128 - 159 coding
;; range, only translates those characters that can be expressed in
;; the corresponding iso-8859 charset.
;; Codepage Mapping:
;;
;; Windows-1250: ISO-8859-2 (Central Europe) - differs in some positions
;; Windows-1251: ISO-8859-5 (Cyrillic) - differs wildly
;; Windows-1252: ISO-8859-1 (West Europe) - exact match
;; Windows-1253: ISO-8859-7 (Greek) - differs in some positions
;; Windows-1254: ISO-8859-9 (Turkish) - exact match
;; Windows-1255: ISO-8859-8 (Hebrew) - exact match
;; Windows-1256: ISO-8859-6 (Arabic) - half match
;; Windows-1257: ISO-8859-4 (Baltic) - differs, future Latin-7
;; Windows-1258: VISCII (Vietnamese) - Completely different
--8<---------------cut here---------------end--------------->8---
I think "exact match" is a little bit misleading, because
e.g. Windows-1252 is a superset of ISO-8859-1. When reading the
comment on the "128 - 159 coding range" carefully it becomes more
clear the mapping table only refers to ISO-8859 code points.
BTW: The comment in `codepage.el' says that Latin-7 isn't official and
the it's not supported by Emacs. This doesn't seem to be correct
anymore.
