Hi Bill,
I'm trying to make BUlleted lists work. The best way to do this
would be to insert a unicode UCS_BULLET into abi. This currently doesn't
work. I have not yet had the time to trace the problem all the way to
Abi's unicode font problems because there are lots of other bugs that have
to be squashed before then, however I suspect that fater all the bugs are
squashed in the list code we still won't be able to display unicode wide
fonts.
hj submitted a patch that enabled abi to write in Chinese but it was never
applied. You might want to look in the archives around March and April and
see what his patch did to the font sets. hj is a very good programmer and
I suspect we may learn a lot from the patch he submitted.
Cheers
Martin
