@ -17,6 +17,13 @@ LATEST CHANGES BETWEEN 2.1.8 and 2.1.7
- The FT_FACE_FLAGS_GLYPH_NAMES is now set correctly for all font
formats.
- Some subsetted Type 1 fonts weren't parsed correctly. This bug
has been introduced in 2.1.7.
- The WinFNT driver now correctly reports FT_ENCODING_NONE for all
but one encoding. Use the new FT_WinFNT_ID_XXX values together
with FT_Get_WinFNT_Header() to get the WinFNT charset ID.

*
* @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.
*
* @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).
