;;; Commentary:

;; This file defines the Emacs charsets and some basic coding systems.
;; Other coding systems are defined in the files in directory
;; lisp/language.

;;; Code:

;;; Remarks

;; The ISO-IR registry is at http://www.itscj.ipsj.or.jp/ISO-IR/.
;; Standards docs equivalent to iso-2022 and iso-8859 are at
;; http://www.ecma.ch/.

;; FWIW, http://www.microsoft.com/globaldev/ lists the following for
;; MS Windows, which are presumably the only charsets we really need
;; to worry about on such systems:
;; `OEM codepages': 437, 720, 737, 775, 850, 852, 855, 857, 858, 862, 866
;; `Windows codepages': 1250, 1251, 1252, 1253, 1254, 1255, 1256, 1257,
;;                      1258, 874, 932, 936, 949, 950

;;; Definitions of character sets.

;; The charsets `ascii', `unicode' and `eight-bit' are already defined
;; in charset.c as below:
