| * 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/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://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers |
| * , |
| * |
| * 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). |
