Thank you for your response! Indeed utf8-string works fine for printing and reading utf8 strings! I would also like to use multibyte characters in GHCi, but as the guys at #Haskell told me yesterday, GHCi 6.10.1 switched from using readline for line edting to the editline lib, and the latter can't handle unicode characters, at least for now. But in GHCi 6.8 and the older versions there shouldn't be any problem with unicode characters in GHCi.

Incidentally, does anyone know the reason that GHCi 6.10.1 switched from using readline to editline?

I think it's because readline uses a GPL license, which technically means that it can't be bundled with GHC since GHC isn't GPL. Why this was suddenly deemed important I'm not sure. -Brent
