Note that "Other_ID_Start" and "Other_ID_Continue" are not categories -- they are properties -- and that unicodedata.category() won't return them, so adding them to these set won't have any effect.  I don't think there's a way to check if chars have that property, but as I said in my previous message it's probably safe to ignore them (nothing will explode even in the unlikely case that those chars are used, right?).

What's the reason for checking if the ord is >= 128?
