Good example. Somebody in Sweden could just go on after
Z with additional letters, which would need two bytes
in UTF-8. But in most places, people will go to AA,
AB, AC,... after Z.

Nice. I just tested, and Emacs (newer version with the
multilingual stuff integrated) does handle such regular
expressions correctly (it doesn't use Unicode or UTF-8
inside, but that's not a problem, it can read and write
Unicode).
