  56    *   FT_WinFNT_ID_XXX
  57    *
  58    * @description:
  59    *   A list of valid values for the `charset' byte in
  60    *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
  61    *   encodings (except for cp1361) can be found at ftp://ftp.unicode.org
  62    *   in the MAPPINGS/VENDORS/MICSFT/WINDOWS subdirectory.  cp1361 is
  63    *   roughly a superset of MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
  64    *
  65    * @values:
  66    *   FT_WinFNT_ID_DEFAULT ::
  67    *     This is used for font enumeration and font creation as a
  68    *     `don't care' value.  Valid font files don't contain this value.
  69    *     When querying for information about the character set of the font
  70    *     that is currently selected into a specified device context, this
  71    *     return value (of the related Windows API) simply denotes failure.
  72    *
  73    *   FT_WinFNT_ID_SYMBOL ::
  74    *     There is no known mapping table available.
  75    *
  76    *   FT_WinFNT_ID_MAC ::
  77    *     Mac Roman encoding.
  78    *
  79    *   FT_WinFNT_ID_OEM ::
  80    *     From Michael Pöttgen <michael@poettgen.de>:
  81    *
  82    *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
  83    *       is used for the charset of vector fonts, like `modern.fon',
  84    *       `roman.fon', and `script.fon' on Windows.
  85    *
  86    *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
  87    *       specifies a character set that is operating-system dependent.
  88    *
  89    *       The `IFIMETRICS' documentation from the `Windows Driver
  90    *       Development Kit' says: This font supports an OEM-specific
  91    *       character set.  The OEM character set is system dependent.
  92    *
  93    *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
  94    *       second default codepage that most international versions of
  95    *       Windows have.  It is one of the OEM codepages from
  96    *
  97    *         http://www.microsoft.com/globaldev/reference/cphome.mspx,
  98    *
  99    *       and is used for the `DOS boxes', to support legacy applications.
 100    *       A German Windows version for example usually uses ANSI codepage
 101    *       1252 and OEM codepage 850.
 102    *
 103    *   FT_WinFNT_ID_CP874 ::
 104    *     A superset of Thai TIS 620 and ISO 8859-11.
 105    *
 106    *   FT_WinFNT_ID_CP932 ::
 107    *     A superset of Japanese Shift-JIS (with minor deviations).
 108    *
 109    *   FT_WinFNT_ID_CP936 ::
 110    *     A superset of simplified Chinese GB 2312-1980 (with different
 111    *     ordering and minor deviations).
 112    *
 113    *   FT_WinFNT_ID_CP949 ::
 114    *     A superset of Korean Hangul KS~C 5601-1987 (with different
 115    *     ordering and minor deviations).
 116    *
 117    *   FT_WinFNT_ID_CP950 ::

 119    *     ordering and minor deviations).
 120    *
 121    *   FT_WinFNT_ID_CP1250 ::
 122    *     A superset of East European ISO 8859-2 (with slightly different
 123    *     ordering).
 124    *
 125    *   FT_WinFNT_ID_CP1251 ::
 126    *     A superset of Russian ISO 8859-5 (with different ordering).
 127    *
 128    *   FT_WinFNT_ID_CP1252 ::
 129    *     ANSI encoding.  A superset of ISO 8859-1.
 130    *
 131    *   FT_WinFNT_ID_CP1253 ::
 132    *     A superset of Greek ISO 8859-7 (with minor modifications).
 133    *
 134    *   FT_WinFNT_ID_CP1254 ::
 135    *     A superset of Turkish ISO 8859-9.
 136    *
 137    *   FT_WinFNT_ID_CP1255 ::

 140    *   FT_WinFNT_ID_CP1256 ::

 145    *
 146    *   FT_WinFNT_ID_CP1258 ::

 148    *     characters.
 149    *
 150    *   FT_WinFNT_ID_CP1361 ::
