In particular, locale also matters for collation. So the desire to
collate Unicode strings properly is reasonable, but you need to know
what locale to use for collation. With Python's current locale model,
one would convert the Unicode string to the locale's encoding, and
then perform collation.

Of course, with an ICU wrapper, you could have multiple simultaneous
locales, and collate Unicode strings without converting them into byte
strings first.
