So long as ASCII regexps will still match UTF-8 strings as if they
were UTF-8 regexps -- i.e. regexps are silently coerced back to UTF-8
when necessary -- I don't see a problem.

I was just surprised that UTF-8 regexps were sometimes silently
converted to ASCII, and that regexps declared with // were ASCII by
default even if I had declared that I wanted UTF-8. I wondered if
there was a reason for doing all that extra processing that I was
missing.
