Why limiting to UTF-8? Since LC_CTYPE locale is widely used not
only for UTF-8 encodings but also for various encodings, and since
GNU Emacs supports such various encodings, I think it is a good idea
to use LC_CTYPE locale not only for detecting UTF-8 mode but also
for detecting other encodings such as ISO-8859-*, KOI8-*, EUC-*,
TIS-620, Big5, and so on.
