<HTML>I've played around with StrokeIt to determine what the "shapes" of each character will be recognized by. I've created a webpage with that lists each <b>built-in</b> character and its shape(s).

The broken image links exist because I don't know the shape of that letter, for example 'X' and 'K'. I looked at Palm/Handspring's Graffiti system and StrokeIt doesn't use those shapes for 'X' and 'K'.
