[Devel] Enumerating font encoding

[Keith Packard]

In attempting to provide additional matching capabilities for applications,
I need to enumerate the set of encoded chars in a font.  Using the 
existing FreeType API (FT_Get_Char_Index) is very expensive, even though 
I'm caching the result -- it takes a second or so to scan each font for 
glyphs from 0 to 0x200000.  Even a hint as to the maximum unicode value 
would obviously be very helpful, but some mechanism for listing the values 
instead would be best.

Anyone have an idea?
