I find it slightly ironic that you pointed out the ASCII limitation while overlooking the arbitrariness of upper/lower-case equivalence. Case isn't the only type of equivalence; it's just the only one which affects ASCII. Should we also have flags to treat half-width and full-width characters as equivalent? What about traditional and simplified Chinese, hiragana and katakana, or the various stylistic variants of the Latin and Greek alphabets in the mathematical symbols block (U+1D400..U+1D7FF)? -- http://mail.python.org/mailman/listinfo/python-list
