type String = [Char]
-{-| The character type 'Char' is an enumeration whose values represent
-Unicode (or equivalently ISO\/IEC 10646) characters
-(see <http://www.unicode.org/> for details).
-This set extends the ISO 8859-1 (Latin-1) character set
-(the first 256 charachers), which is itself an extension of the ASCII
-character set (the first 128 characters).
-A character literal in Haskell has type 'Char'.
-
-To convert a 'Char' to or from the corresponding 'Int' value defined
-by Unicode, use 'Prelude.toEnum' and 'Prelude.fromEnum' from the
-'Prelude.Enum' class respectively (or equivalently 'ord' and 'chr').
