Exact mapping tables for the various cpXXXX * encodings (except for cp1361) can be found at * ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS * subdirectory. cp1361 is roughly a superset of * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT. * * @values: * FT_WinFNT_ID_DEFAULT :: * This is used for font enumeration and font creation as a * `don't care' value. Valid font files don't contain this value. * When querying for information about the character set of the font * that is currently selected into a specified device context, this * return value (of the related Windows API) simply denotes failure. * * FT_WinFNT_ID_SYMBOL :: * There is no known mapping table available. * * FT_WinFNT_ID_MAC :: * Mac Roman encoding. * * FT_WinFNT_ID_OEM :: * From Michael Poettgen <michael@poettgen.de>: * * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM * is used for the charset of vector fonts, like `modern.fon', * `roman.fon', and `script.fon' on Windows. * * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value * specifies a character set that is operating-system dependent. * * The `IFIMETRICS' documentation from the `Windows Driver * Development Kit' says: This font supports an OEM-specific * character set. The OEM character set is system dependent. * * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the * second default codepage that most international versions of * Windows have. It is one of the OEM codepages from * * https://msdn.microsoft.com/en-us/goglobal/bb964655, * * and is used for the `DOS boxes', to support legacy applications. * A German Windows version for example usually uses ANSI codepage * 1252 and OEM codepage 850. * * FT_WinFNT_ID_CP874 :: * A superset of Thai TIS 620 and ISO 8859-11. * * FT_WinFNT_ID_CP932 :: * A superset of Japanese Shift-JIS (with minor deviations). * * FT_WinFNT_ID_CP936 :: * A superset of simplified Chinese GB 2312-1980 (with different * ordering and minor deviations). * * FT_WinFNT_ID_CP949 :: * A superset of Korean Hangul KS~C 5601-1987 (with different * ordering and minor deviations). * * FT_WinFNT_ID_CP950 :: * A superset of traditional Chinese Big~5 ETen (with different * ordering and minor deviations). * * FT_WinFNT_ID_CP1250 :: * A superset of East European ISO 8859-2 (with slightly different * ordering). * * FT_WinFNT_ID_CP1251 :: * A superset of Russian ISO 8859-5 (with different ordering). * * FT_WinFNT_ID_CP1252 :: * ANSI encoding. A superset of ISO 8859-1. * * FT_WinFNT_ID_CP1253 :: * A superset of Greek ISO 8859-7 (with minor modifications). * * FT_WinFNT_ID_CP1254 :: * A superset of Turkish ISO 8859-9. * * FT_WinFNT_ID_CP1255 :: * A superset of Hebrew ISO 8859-8 (with some modifications). * * FT_WinFNT_ID_CP1256 :: * A superset of Arabic ISO 8859-6 (with different ordering). * * FT_WinFNT_ID_CP1257 :: * A superset of Baltic ISO 8859-13 (with some deviations). * * FT_WinFNT_ID_CP1258 :: * For Vietnamese.
