|
|||
- 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.

* A list of valid values for the `charset' byte in

|

* @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).

|
||||
* A superset of simplified Chinese GB 2312-1980 (with different

* ordering and minor deviations).
|
||||
*
|
||||
* FT_WinFNT_ID_CP949 ::
