The ghc standard libraries only work with latin1, however, there are
quite a few libraries out there for reading/writing text in the current
locale (or a set format like UTF-8) so ghcs limitations are not too bad
in practice if you need unicode. Some are even drop-in replacements for
the standard prelude IO functions.
It should also be said that these are limitations of the current haskell
tools and not the language itself, the language specifies unicode and
leaves the details of IO up to implementations.
