Exact mapping tables for the various cpXXXX 61 * encodings (except for cp1361) can be found at 62 * ftp://ftp.unicode.org/public in the MAPPINGS/VENDORS/MICSFT/WINDOWS 63 * subdirectory. cp1361 is roughly a superset of 64 * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT. 65 * 66 * @values: 67 * FT_WinFNT_ID_DEFAULT :: 68 * This is used for font enumeration and font creation as a 69 * `don't care' value. Valid font files don't contain this value. 70 * When querying for information about the character set of the font 71 * that is currently selected into a specified device context, this 72 * return value (of the related Windows API) simply denotes failure. 73 * 74 * FT_WinFNT_ID_SYMBOL :: 75 * There is no known mapping table available. 76 * 77 * FT_WinFNT_ID_MAC :: 78 * Mac Roman encoding. 79 * 80 * FT_WinFNT_ID_OEM :: 81 * From Michael Pöttgen <michael@poettgen.de>: 82 * 83 * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM 84 * is used for the charset of vector fonts, like `modern.fon', 85 * `roman.fon', and `script.fon' on Windows. 86 * 87 * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value 88 * specifies a character set that is operating-system dependent. 89 * 90 * The `IFIMETRICS' documentation from the `Windows Driver 91 * Development Kit' says: This font supports an OEM-specific 92 * character set. The OEM character set is system dependent. 93 * 94 * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the 95 * second default codepage that most international versions of 96 * Windows have.
