Glyphs of selected text??

Hi
I'm very newbie to WPF (in fact to .Net).

I'm looking for some example regarding to get the list of Glyphs (from a number of fonts) of a text character written in a text box or rich text box.

Or

For the sake of getting the idea, how can we display Glyph for a character in a sentence written in a text box and use that Glyph to get list from other fonts?


Thanks a lot.
