I have a suspicion that by using different XLFDs with same font name but
different encoding field it will be possible to get all characters from font
displayed (probably by using XFont with the encoding field in xlfd that has
the character being drawn in it). May be creating a fontset from XLFDs with
the same font name and different encoding field will work and will allow not
to switch XFont when drawing each character, and will allow to utilize all
glyphs in given font?
I think these questions should better be asked to XFree team.
Another option I think worth considering is to inspect what gtk-2.0 uses (it
uses Pango - and what mechanism pango uses?). I saw a screenshots of pango
showing a lot of various languages in one text widget. Have anybody tried
gtk-2.0 betas? May be these quesions should be asked to
gtk-devel-list@gnome.org? If this problem is solved, may be we should wait for
gtk-2.0 and don't bother with utf8 input and drawing and concentrate on
printing?
