what's the C-q 377 char?

if i press Ctrl+q 377 Enter, i get this char: ÿ, which is LATIN SMALL
LETTER Y WITH DIAERESIS (unicode U+00FF).

Then if i do:

(re-search-forward "ÿ")
ÿ

it works perfectly.

as far as my experience goes, the ease of programing with unicode in
elisp beats Perl and Python hands down...
