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 ::
118   *     A superset of traditional Chinese Big~5 ETen (with different
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 ::
138   *     A superset of Hebrew ISO 8859-8 (with some modifications).
139   *
140   *   FT_WinFNT_ID_CP1256 ::
141   *     A superset of Arabic ISO 8859-6 (with different ordering).
142   *
143   *   FT_WinFNT_ID_CP1257 ::
144   *     A superset of Baltic ISO 8859-13 (with some deviations).
145   *
146   *   FT_WinFNT_ID_CP1258 ::
147   *     For Vietnamese.  This encoding doesn't cover all necessary
148   *     characters.
149   *
150   *   FT_WinFNT_ID_CP1361 ::
