That is very interesting. I was working off of the Microsoft typography website
where it states font requirements. I also know that native usp10.dll does in
fact reject some TTF fonts even if they do have the glyphs.

If you make fonts is there a chance you could create me a set of dummy fonts
that have some of the features but not all?  That way I can do some empirical
testing as to what uniscribe actually requires or not? 

thanks!
