This is awesome, and it works. My only quibble is that it doesn't seem to handle accented characters, ie it finds \aa, presumably because that's a single symbol

This is awesome, and it works. My only quibble is that it doesn't seem to handle accented characters, ie it finds \aa, presumably because that's a single symbol, but it doesn't find \"{a} and it doesn't even seem to show up in the training list.
