Aah, ok, I didn't get what you were saying. I thought `utf-8' here would just give me back the original. OK, so I really need
(length (encode-coding-string "EURO" 'utf-8))
and actually, since the process can be using a different encoding, I need
(length (encode-coding-string "EURO" my-encoding))
Thanks! I already pushed a quick fix, but this seems more solid.
