The text-icu library is the more practical cousin to the text library, implementing a myriad of Unicode-related functionality that is not yet otherwise available in Haskell. It is implemented as bindings to the widely used ICU library. http://hackage.haskell.org/package/text-icu Features: - Locale sensitive case mapping. - Text normalization. (What is normalization? http://unicode.org/faq/normalization.html) - [NEW] Locale sensitive string collation. - Conversion to and from a huge number of native encodings. - [NEW] Efficient comparison of ByteString and Text. The library is thoroughly documented, and most interfaces are pure and easy to use. Look for further releases over the coming weeks as I complete the ICU integration.
