How to tell if a font is fixed pitch, variable pitch, serifed, sa ns, etc.

[Pedriana, Paul]

I see that you can tell the family name of a font in FreeType2 and the 
style (bold, italic), but I can't see anywhere where I can find if the font 
is fixed pitch, sans serif, etc. I need this information so I can write a 
font server whereby clients can ask for a fixed pitch font, for example.

Also, I noticed that bold and italic sytle flags are defined, but no others.

Another issue is that I can't find out how to enumerate the available 
characters in a font. I can load a given character, but can find no way
to have it give me a list of available characters.

Any answers?
