[Haskell-beginners] Re: Unicode in GHCi

[Christos Chryssochoidis]

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.

Thanks very much again!

Christos
