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.
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.
74 * FT_WinFNT_ID_SYMBOL ::
75 * There is no known mapping table available.
81 * From Michael Pöttgen <michael@poettgen.de>:
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.
87 * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
88 * specifies a character set that is operating-system dependent.
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.
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
98 * http://www.microsoft.com/globaldev/reference/cphome.mspx,
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.
104 * FT_WinFNT_ID_CP874 ::
105 * A superset of Thai TIS 620 and ISO 8859-11.
107 * FT_WinFNT_ID_CP932 ::
108 * A superset of Japanese Shift-JIS (with minor deviations).
110 * FT_WinFNT_ID_CP936 ::
111 * A superset of simplified Chinese GB 2312-1980 (with different
112 * ordering and minor deviations).
114 * FT_WinFNT_ID_CP949 ::
115 * A superset of Korean Hangul KS~C 5601-1987 (with different
116 * ordering and minor deviations).
118 * FT_WinFNT_ID_CP950 ::
119 * A superset of traditional Chinese Big~5 ETen (with different
120 * ordering and minor deviations).
122 * FT_WinFNT_ID_CP1250 ::
123 * A superset of East European ISO 8859-2 (with slightly different
126 * FT_WinFNT_ID_CP1251 ::
127 * A superset of Russian ISO 8859-5 (with different ordering).
129 * FT_WinFNT_ID_CP1252 ::
130 * ANSI encoding. A superset of ISO 8859-1.
132 * FT_WinFNT_ID_CP1253 ::
133 * A superset of Greek ISO 8859-7 (with minor modifications).
135 * FT_WinFNT_ID_CP1254 ::
136 * A superset of Turkish ISO 8859-9.
138 * FT_WinFNT_ID_CP1255 ::
139 * A superset of Hebrew ISO 8859-8 (with some modifications).
141 * FT_WinFNT_ID_CP1256 ::
142 * A superset of Arabic ISO 8859-6 (with different ordering).
144 * FT_WinFNT_ID_CP1257 ::
145 * A superset of Baltic ISO 8859-13 (with some deviations).
147 * FT_WinFNT_ID_CP1258 ::
148 * For Vietnamese. This encoding doesn't cover all necessary
