Where can I find good info on glyphs?

[jonathon]

I've checked the Cocoa docs and the GNUstep docs, and there is next to
nothing.  How can I find out how to look up a glyph and then append it
to a bezier path?

I have found a lot of partial docs and to-be-done docs, but nothing
definitive.  The closest I got was NSFont glyphWithName, which tells
me to 'look up the glyph on my own.'
