I'd need to do a bit of research, but as I recall all traditional
characters are only simplified one way, yes. Sometimes multiple
traditional characters will turn into the same simplified one, but I
don't think one character can be simplified multiple ways.

Okay, so I'd first "downcase" the string to simplified characters, then
do the lookup. That could be doable...

Thanks!
