No, unfortunately -- that would make everything much easier. Eventually
the idea will be to decode the strings into plain utf-8-emacs, but for
now I'm stuck keeping them in this weird half-state. I literally need a
conversion between the two versions above.

If this turns out to be too ridiculous, I'll re-slice things as I
mentioned earlier, and leave these group names as symbols.
