Hi Kyle,
I will try to get the glyph name somewhere on the unicode website.
Instead of the methods you suggest I will use:
NSGlyph name = [font glyphWithName:@"summation"];
Thanks.

not all, at the same time, but single characters when needed in a

Sounds like you're subverting the Cocoa text system. Not a good idea.
Perhaps you should subclass NSLayoutManager to create custom text
containers, and NSTypesetter to lay out your math text.
For unicode characters in the 16 bits range I use the following code:
NSGlyph glyph = [font _defaultGlyphForChar:ch];
I don't see this method documented anywhere. Meanwhile, CTFont has
CTFontGetGlyphsForCharacters and CTFontGetGlyphWithName (which is what
you're probably going to want).
