How can I get a list of valid characters in a particular font. For instance, the end user of my app selects a font from a popup menu, say "American Typewriter." I want to then have another popup give a choice of all the characters available in the American Typewriter font. To do that, I need a list of the characters found in that font. Needless to say, I don't want the list to contain any null or missing characters. Hopefully this makes sense.
Thanks in advance,
Mark
