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.
