[flash 8] Detecting drawn letters

I’ve been giving thought to this for some time now, but I haven’t been able to this point, to come up with something worth doing…

So, to lay the problem on you guys. Naked scene, nothing on it, and you have this simple drawing thing -> while you press the mouse button and keep it pressed, you draw stuff on the scene, when you release it, no more drawing.

What I am interested in is -> Let’s say you draw a letter. A “R” for example. How could I make flash detect what letter it’s been drawn? My ideas spin around having small, invisible movieclips all over the stage, and then somehow making use of those who’ve been pressed…
But from there on out, it’s a standstill. So, any ideas, because I would sure appreciate any?

Cheers
