our software doesn't know anything about combining characters. If the ttf file 
contains support for the combined character then presumably the characters will 
be drawn correctly. Our code will not render (E,acutesymbol) properly, but 
EACUTE does get rendered properly, so I guess I'm asking if the font contains 
the combinations or just the simple glyphs.
