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
