[Haskell-beginners] Unicode in GHCi

[Christos Chryssochoidis]

Hello,

I'd like to type in GHCi some non-latin characters, but when I try it,
no characters are inserted at all. Latin characters though are typed
in fine, and in any other shell except GHCi I try non-Latin characters
get typed without problem.

I mean I'm not able to type in GHCi an expression like

'ᾶ' == 'ᾶ'    (can't type in the ᾶ)

Is this a known GHCi restriction on the character set it accepts, or
something is wrong with my setup of GHCi/terminal?

I'm using GHC 6.10.1 in Mac OS X Terminal.

Thank you very much,

Christos
