     * @enum:
     *   FT_WinFNT_ID_XXX
     *
     * @description:
     *   A list of valid values for the `charset' byte in
     *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
     *   encodings (except for cp1361) can be found at
     *   ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
     *   subdirectory.  cp1361 is roughly a superset of
     *   MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
     *
     * @values:
     *   FT_WinFNT_ID_DEFAULT ::
     *     This is used for font enumeration and font creation as a
     *     `don't care' value.  Valid font files don't contain this value.
     *     When querying for information about the character set of the font
     *     that is currently selected into a specified device context, this
     *     return value (of the related Windows API) simply denotes failure.
     *
     *   FT_WinFNT_ID_SYMBOL ::
     *     There is no known mapping table available.
     *
     *   FT_WinFNT_ID_MAC ::
     *     Mac Roman encoding.
     *
     *   FT_WinFNT_ID_OEM ::
     *     From Michael Poettgen <michael@poettgen.de>:
     *
     *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
     *       is used for the charset of vector fonts, like `modern.fon',
     *       `roman.fon', and `script.fon' on Windows.
     *
     *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
     *       specifies a character set that is operating-system dependent.
     *
     *       The `IFIMETRICS' documentation from the `Windows Driver
     *       Development Kit' says: This font supports an OEM-specific
     *       character set.  The OEM character set is system dependent.
     *
     *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
     *       second default codepage that most international versions of
     *       Windows have.  It is one of the OEM codepages from
     *
     *         https://msdn.microsoft.com/en-us/goglobal/bb964655,
     *
     *       and is used for the `DOS boxes', to support legacy applications.
     *       A German Windows version for example usually uses ANSI codepage
     *       1252 and OEM codepage 850.
     *
     *   FT_WinFNT_ID_CP874 ::
     *     A superset of Thai TIS 620 and ISO 8859-11.
     *
     *   FT_WinFNT_ID_CP932 ::
     *     A superset of Japanese Shift-JIS (with minor deviations).
     *
     *   FT_WinFNT_ID_CP936 ::
     *     A superset of simplified Chinese GB 2312-1980 (with different
     *     ordering and minor deviations).
     *
     *   FT_WinFNT_ID_CP949 ::
     *     A superset of Korean Hangul KS~C 5601-1987 (with different
     *     ordering and minor deviations).
     *
     *   FT_WinFNT_ID_CP950 ::
     *     A superset of traditional Chinese Big~5 ETen (with different
     *     ordering and minor deviations).
     *
     *   FT_WinFNT_ID_CP1250 ::
     *     A superset of East European ISO 8859-2 (with slightly different
     *     ordering).
     *
     *   FT_WinFNT_ID_CP1251 ::
     *     A superset of Russian ISO 8859-5 (with different ordering).
     *
     *   FT_WinFNT_ID_CP1252 ::
     *     ANSI encoding.  A superset of ISO 8859-1.
     *
     *   FT_WinFNT_ID_CP1253 ::
     *     A superset of Greek ISO 8859-7 (with minor modifications).
     *
     *   FT_WinFNT_ID_CP1254 ::
     *     A superset of Turkish ISO 8859-9.
     *
     *   FT_WinFNT_ID_CP1255 ::
     *     A superset of Hebrew ISO 8859-8 (with some modifications).
     *
     *   FT_WinFNT_ID_CP1256 ::
     *     A superset of Arabic ISO 8859-6 (with different ordering).
     *
     *   FT_WinFNT_ID_CP1257 ::
     *     A superset of Baltic ISO 8859-13 (with some deviations).
     *
     *   FT_WinFNT_ID_CP1258 ::
     *     For Vietnamese.  This encoding doesn't cover all necessary
     *     characters.
     *
     *   FT_WinFNT_ID_CP1361 ::
     *     Korean (Johab).
