So what you are looking for is a kind of file descriptor listing the 
font's capabilities about unicode sygns, right? I don't know if such file 
is available for easy grepping. My understanting (I can be wrong, of 
course) is that such features are hard-coded within font system libraries 
(as "Pango" in GTK, etc...) :-?

I think standard letters are treated slightly different than extended 
unicode characters.
