michael@0 55 * @enum:
michael@0 56 * FT_WinFNT_ID_XXX
michael@0 57 *
michael@0 58 * @description:
michael@0 59 * A list of valid values for the `charset' byte in
michael@0 60 * @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX
michael@0 61 * encodings (except for cp1361) can be found at
michael@0 62 * ftp://ftp.unicode.org/public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
michael@0 63 * subdirectory. cp1361 is roughly a superset of
michael@0 64 * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
michael@0 65 *
michael@0 66 * @values:
michael@0 67 * FT_WinFNT_ID_DEFAULT ::
michael@0 68 * This is used for font enumeration and font creation as a
michael@0 69 * `don't care' value. Valid font files don't contain this value.
michael@0 70 * When querying for information about the character set of the font
michael@0 71 * that is currently selected into a specified device context, this
michael@0 72 * return value (of the related Windows API) simply denotes failure.
michael@0 73 *
michael@0 74 * FT_WinFNT_ID_SYMBOL ::
michael@0 75 * There is no known mapping table available.
michael@0 76 *
michael@0 77 * FT_WinFNT_ID_MAC ::
michael@0 78 * Mac Roman encoding.
michael@0 79 *
michael@0 80 * FT_WinFNT_ID_OEM ::
michael@0 81 * From Michael Pöttgen <michael@poettgen.de>:
michael@0 82 *
michael@0 83 * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
michael@0 84 * is used for the charset of vector fonts, like `modern.fon',
michael@0 85 * `roman.fon', and `script.fon' on Windows.
michael@0 86 *
michael@0 87 * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
michael@0 88 * specifies a character set that is operating-system dependent.
michael@0 89 *
michael@0 90 * The `IFIMETRICS' documentation from the `Windows Driver
michael@0 91 * Development Kit' says: This font supports an OEM-specific
michael@0 92 * character set. The OEM character set is system dependent.
michael@0 93 *
michael@0 94 * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
michael@0 95 * second default codepage that most international versions of
michael@0 96 * Windows have. It is one of the OEM codepages from
michael@0 97 *
michael@0 98 * http://www.microsoft.com/globaldev/reference/cphome.mspx,
michael@0 99 *
michael@0 100 * and is used for the `DOS boxes', to support legacy applications.
michael@0 101 * A German Windows version for example usually uses ANSI codepage
michael@0 102 * 1252 and OEM codepage 850.
michael@0 103 *
michael@0 104 * FT_WinFNT_ID_CP874 ::
michael@0 105 * A superset of Thai TIS 620 and ISO 8859-11.
michael@0 106 *
michael@0 107 * FT_WinFNT_ID_CP932 ::
michael@0 108 * A superset of Japanese Shift-JIS (with minor deviations).
michael@0 109 *
michael@0 110 * FT_WinFNT_ID_CP936 ::
michael@0 111 * A superset of simplified Chinese GB 2312-1980 (with different
michael@0 112 * ordering and minor deviations).
michael@0 113 *
michael@0 114 * FT_WinFNT_ID_CP949 ::
michael@0 115 * A superset of Korean Hangul KS~C 5601-1987 (with different
michael@0 116 * ordering and minor deviations).
michael@0 117 *
michael@0 118 * FT_WinFNT_ID_CP950 ::
michael@0 119 * A superset of traditional Chinese Big~5 ETen (with different
michael@0 120 * ordering and minor deviations).
michael@0 121 *
michael@0 122 * FT_WinFNT_ID_CP1250 ::
michael@0 123 * A superset of East European ISO 8859-2 (with slightly different
michael@0 124 * ordering).
michael@0 125 *
michael@0 126 * FT_WinFNT_ID_CP1251 ::
michael@0 127 * A superset of Russian ISO 8859-5 (with different ordering).
michael@0 128 *
michael@0 129 * FT_WinFNT_ID_CP1252 ::
michael@0 130 * ANSI encoding. A superset of ISO 8859-1.
michael@0 131 *
michael@0 132 * FT_WinFNT_ID_CP1253 ::
michael@0 133 * A superset of Greek ISO 8859-7 (with minor modifications).
michael@0 134 *
michael@0 135 * FT_WinFNT_ID_CP1254 ::
michael@0 136 * A superset of Turkish ISO 8859-9.
michael@0 137 *
michael@0 138 * FT_WinFNT_ID_CP1255 ::
michael@0 139 * A superset of Hebrew ISO 8859-8 (with some modifications).
michael@0 140 *
michael@0 141 * FT_WinFNT_ID_CP1256 ::
michael@0 142 * A superset of Arabic ISO 8859-6 (with different ordering).
michael@0 143 *
michael@0 144 * FT_WinFNT_ID_CP1257 ::
michael@0 145 * A superset of Baltic ISO 8859-13 (with some deviations).
michael@0 146 *
michael@0 147 * FT_WinFNT_ID_CP1258 ::
michael@0 148 * For Vietnamese. This encoding doesn't cover all necessary
michael@0 149 * characters.
michael@0 150 *
michael@0 151 * FT_WinFNT_ID_CP1361 ::
michael@0 152 * Korean (Johab).
