CHANGES BETWEEN 2.4.4 and 2.4.5
I. MISCELLANEOUS
- Support for PCF files compressed with bzip2 has been contributed
by Joel Klinghed. To make this work, the OS must provide a
bzip2 library.

Encodings
*********
The variety of encodings that accompanies pcf fonts appears to encompass the
small set defined in freetype.h. On the other hand, each pcf font defines
two properties that specify encoding and registry.
Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
I decided to make these two properties directly accessible, leaving to the
client application the work of interpreting them. For instance:
#include "pcftypes.h" /* include/freetype/internal/pcftypes.h */
FT_Face face;
PCF_Public_Face pcfface;
FT_New_Face( library,..., &face );
pcfface = (PCF_Public_Face)face;
if ((pcfface->charset_registry == "ISO10646") &&
(pcfface->charset_encoding) == "1")) [..]
Thus the driver always export `ft_encoding_none' as
face->charmap.encoding. FT_Get_Char_Index() behavior is unmodified, that
is, it converts the ULong value given as argument into the corresponding
glyph number.
