Do not assume anything about the ordering of the characters.
The lowercase letters may come before or after the uppercase letters;
-the lowercase and uppercase may be interlaced so that both `a' and `A'
-come before `b'; the accented and other international characters may
-be interlaced so that E<auml> comes before `b'.
