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)?
