during a late hacking pass, I was perplexed to realized that r"[\u0000-\uffff]" didn't match any unicode character, and reported it as bug #420011. but a few minutes later, I realized that SRE doesn't support \u and \U escapes at all -- and that the pattern u"[\u0000-\uffff]" works as expected. should I close the bug report, or turn it into a feature request? </F>
