This library implements @i;unicode-casemap@,
the simple, non locale-sensitive unicode collation
algorithm described in RFC 5051 (<http://www.rfc-editor.org/rfc/rfc5051.txt>).
Proper unicode collation can be done using text-icu, but that is a big
dependency that depends on a large C library, and rfc5051 might be better
for some purposes.
Here is a list of strings sorted by the Prelude's @sort@ function:
@Abe Oeb abe abé oeb Ábe Äbe Ôeb ábe äbe ôeb@
Here is the same list sorted by @sortBy compareUnicode@:
@Abe abe abé Ábe ábe Äbe äbe Oeb oeb Ôeb ôeb@
