Actually, that isn't the full truth; see UAX#21, which is now official
part of Unicode 4. It specifies two kinds of case conversion:
simple case conversion, and full case conversion. Python only supports
simple case conversion at the moment. Full case conversion is context
(locale) dependent, and must take into account SpecialCasing.txt.
