haskell build codes generator itself 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 ab&#233; oeb &#193;be &#196;be &#212;eb &#225;be &#228;be &#244;eb@ Here is the same list sorted by @sortBy compareUnicode@: @Abe abe ab&#233; &#193;be &#225;be &#196;be &#228;be Oeb oeb &#212;eb &#244;eb@
