haskell Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms. Features include: * Both pure and impure bindings, to allow for fine control over efficiency and ease of use. * Breaking of strings on character, word, sentence, and line boundaries. * Access to the Unicode Character Database (UCD) of character metadata. * String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes. * Character set conversion functions, allowing conversion between Unicode and over 220 character encodings. * Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.) * Regular expression search and replace. bos/text-icu
