  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
  62    *   ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
  63    *   subdirectory.  cp1361 is roughly a superset of
  64    *   MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
  65    *
  66    * @values:
  67    *   FT_WinFNT_ID_DEFAULT ::
  68    *     This is used for font enumeration and font creation as a
  69    *     `don't care' value.  Valid font files don't contain this value.
  70    *     When querying for information about the character set of the font
  71    *     that is currently selected into a specified device context, this
  72    *     return value (of the related Windows API) simply denotes failure.
  73    *
  74    *   FT_WinFNT_ID_SYMBOL ::
  75    *     There is no known mapping table available.
  76    *
  77    *   FT_WinFNT_ID_MAC ::
  78    *     Mac Roman encoding.
  79    *
  80    *   FT_WinFNT_ID_OEM ::
  81    *     From Michael Pöttgen <michael@poettgen.de>:
  82    *
  83    *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
  84    *       is used for the charset of vector fonts, like `modern.fon',
  85    *       `roman.fon', and `script.fon' on Windows.
  86    *
  87    *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
  88    *       specifies a character set that is operating-system dependent.
  89    *
  90    *       The `IFIMETRICS' documentation from the `Windows Driver
  91    *       Development Kit' says: This font supports an OEM-specific
  92    *       character set.  The OEM character set is system dependent.
  93    *
  94    *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
  95    *       second default codepage that most international versions of
  96    *       Windows have.  It is one of the OEM codepages from
  97    *
  98    *         https://msdn.microsoft.com/en-us/goglobal/bb964655,
  99    *
 100    *       and is used for the `DOS boxes', to support legacy applications.
 101    *       A German Windows version for example usually uses ANSI codepage
 102    *       1252 and OEM codepage 850.
 103    *
 104    *   FT_WinFNT_ID_CP874 ::
 105    *     A superset of Thai TIS 620 and ISO 8859-11.
 106    *
 107    *   FT_WinFNT_ID_CP932 ::
 108    *     A superset of Japanese Shift-JIS (with minor deviations).
 109    *
 110    *   FT_WinFNT_ID_CP936 ::
 111    *     A superset of simplified Chinese GB 2312-1980 (with different
 112    *     ordering and minor deviations).
 113    *
 114    *   FT_WinFNT_ID_CP949 ::
 115    *     A superset of Korean Hangul KS~C 5601-1987 (with different

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

 146    *
 147    *   FT_WinFNT_ID_CP1258 ::

 150    *
 151    *   FT_WinFNT_ID_CP1361 ::
