Do you know of the stix project?
I haven't had time to fully investigate these yet but I thought we might
be able to use them.

Very true. I was hoping we could have a small subset of interesting fonts
for bullets and Dingbats type symbols.
If this doesn't work out I suggest we implement a remapping table to map
the correct unicode glyphs to our Symbol and Dingbat fonts. I think its
the only way we can maintain XP compatibility of various interesting
bullet type symbols.

I *think* we have the infrastructure in place to this should we not find a
good set of Type 1 unicode fonts.
Should this not work out my own personal preference would be to use ttf
fonts and require that abi be used with ttf font server on Unix. Xfree
supports this so other X implementations should too.
