Get path to trace out a character in an iOS UIFont

Suppose I have a custom font "Foo" that I'm using in my iOS App. I've added it to my project, plist, etc. and I'm able to render UILabels and such with it just fine.

Now, if I want to find out a sequence of points that would "trace out" the letter 'P' in that font, how would I get that sequence of points? For example, suppose I wanted to use a CGPath to draw the letter 'P' slowly like a plotter would ...

I just need a sequence of CGPoints in an array that if drawn as a path would draw a 'P'.

I realize that for some letters like 'T', this may not make sense, since the pen would have to be lifted to cross the 'T'. So maybe I need a sequence of CGPaths ...

Any hints on how to accomplish this?

Thanks!
