* @enum: |
|
* FT_WinFNT_ID_XXX |
|
* |
|
* @description: |
|
* A list of valid values for the `charset' byte in |
|
* @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX |
|
* encodings (except for cp1361) can be found at ftp://ftp.unicode.org |
|
* 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 Pöttgen <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 |
|
* |
|
* http://www.microsoft.com/globaldev/reference/cphome.mspx, |
|
* |
|
* 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. This encoding doesn't cover all necessary |
|
* characters. |
|
* |
|
* FT_WinFNT_ID_CP1361 :: |
|
* Korean (Johab). |
