I think most people on p5p agree.

The problem lies waaaaaaaaaaay back, when it was decided that, in the
absence of a location in effect, none of the characters in the 128..255
range ought to be considered 'word' characters. So they don't match \w,
and are uneffected by uc/lc.

Then we got Unicode and UTF-8. But we also don't want to break existing
code. So we continue to let the "wordness" of the characters of 128..255
for non-UTF-8 strings to be determined by the locale.

I wouldn't mind having a feature (or a pragma), that says "use Unicode
semantics, regardless how the string is encoded".
