| 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 :: | |
