Well, if you were satisfied with a collation based on binary
representations of characters (as I am) your keys will be
the same size as your strings. Each feature you add (J & j
sorting near each other, accents, special space characters) adds
something. Case adds one bit per character, rounded to the
nearest byte. Accents add more.
