  39 ;; The ISO-IR registry is at http://www.itscj.ipsj.or.jp/ISO-IR/.
  40 ;; Standards docs equivalent to iso-2022 and iso-8859 are at
  41 ;; http://www.ecma.ch/.
  42
  43 ;; FWIW, http://www.microsoft.com/globaldev/ lists the following for
  44 ;; MS Windows, which are presumably the only charsets we really need
  45 ;; to worry about on such systems:
  46 ;; `OEM codepages': 437, 720, 737, 775, 850, 852, 855, 857, 858, 862, 866
  47 ;; `Windows codepages': 1250, 1251, 1252, 1253, 1254, 1255, 1256, 1257,
  48 ;;                      1258, 874, 932, 936, 949, 950
