Unicode support (was Re: Calling all beta testers! Re: gEDA-user: Check for same refdes)

Hi all,
I'm moving this thread to geda-dev, as the theme is changing to Unicode
support and development issues.

The patch didn't break support for gtk+ 1.2.x . It just adds support for
Unicode when using gtk+ 2.x, and leave things as they were when using
gtk+ 1.2.x . It can be found at:
http://archives.seul.org/geda/dev/Oct-2003/msg00071.html

Just reviewing what I wrote (I don't trust my memory after so much
time ;-) ), it improves libgeda to handle the first page of unicode.
Currently, there is defined a font_set array holding all supported
characters. Supporting Unicode with this scheme means having an array of
2^32 bytes in memory, which has no sense for me.
I strongly feel that string support needs to be improved, and it means
changing the font_set scheme. Any ideas?

Cheers,

Carlos
