Your question has inspired me to add a System.Environment.UTF8 module
to utf8-string 0.3.5

This module behaves like the System.IO.UTF8 wrapper.

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.)
