The attached patch implements the necessary changes to allow
printing with Unicode fonts, including ttf fonts. The following is a
summary of what it does:
* implements an XP class UT_AdobeEncoding that handles
conversions from glyph names to ucs and vice versa.
* removes all glyph name tables from the source files. Instead
these tables are located in files with u2g extension residing
the fonts directory, from where they are loaded when needed.
These tables occupy significant resources
(the complete Adobe glyph table occupies around 16K!) but are
only used when creating the PS font class, which only
happens when the PS output is generated; thus for 99% of the
time these are not needed. Further, this system simplifies font
handling and caters for fonts with non-standard glyph names
(dingbats, symbols, MS ttf fonts ...), for which suitable u2g file
can be created.
* removes the UnixFont::getUniWidths() function, replacing it
with getCharWidth( UT_UCSChar). The entire width lookup
mechanism has been rewritten, since the existing one was
unsuitable for 16-bit fonts. (Look up by indexing an array
would require 128K lookup table!)
* makes changes to drawCharsCJK allowing output of
characters by glyph name.
The tarball contains the patch, + files adobe-full.u2g, adobe-
short.u2g, dingbats.u2g and symbol.u2g; these should be copied
to the fonts peer directory, and installed with the fonts.
dingbats.u2g and symbol.u2g need to be further symlinked to
d050000l.u2g and s050000l.u2g respectively. The format of the
u2g files is explained in u2g_format.txt which is also included.
(I have further included files tahoma.afm and tahoma.u2g which can
be used with the MS tahoma Unicode font, for those who wish to
experiment with ttf fonts.)
