More accurately, string I/O (meaning all OS interfaces which take or
return strings, not just reading/writing files) in Haskell is deeply
The Haskell functions accept or return Strings but interface to OS
functions which (at least on Unix) deal with arrays of bytes (char*),
and the encoding issues are essentially ignored. If you pass strings
containing anything other than ISO-8859-1, you lose.
