Char package:base-compat

The character type Char is an enumeration whose values represent Unicode (or equivalently ISO/IEC 10646) code points (i.e. characters, see http://www.unicode.org/ for details). This set extends the ISO 8859-1 (Latin-1) character set (the first 256 characters), 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 toEnum and fromEnum from the Enum class respectively (or equivalently ord and chr).

Character literal

Read a character from the standard input device (same as hGetChar stdin).

Write a character to the standard output device (same as hPutChar stdout).

utility function converting a Char to a show function that simply prepends the character unchanged.
