GHC mangles UTF by default. You probably want to use one of the utf8
packages; eg. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/utf8-string
or http://hackage.haskell.org/cgi-bin/hackage-scripts/package/utf8-light

(Neither of them seems to allow for accessing *arguments* rather than
stdin/stdout, but you could probably do something with the
encoding/decoding functions.)
