+     "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. . * Security checks
+for visually confusable (spoofable) strings. . * Bidirectional Unicode algorithm
+. * Calendar objects holding dates and times. . * Number and calendar
+formatting.")
