[Haskell-cafe] accents

[Dupont Corentin]

Hello,
i'm still struggling with ghci and accents.

Prelude> "é"
"\233"

I've installed GHC 6.12.1, which gave me a better result:

Prelude> putStrLn "é"
é

but still:

Prelude> "é"
"\233"

I'm trying to search a file with french words with Regex, but i
stumble on accents:

*Main> findRegexFile "abnégation"
[]
*Main> findRegexFile "abn.gation"
["abn\218gation","abn\218gations"]


I don't know the encoding of my file, how to deduce it?
What is the encoding used by ghci? Unicode?
Its seems not be the same since the représentation for "é" is not the
same (\233 and \218).
How to have accented characters in ghci? Can't find any ressources on the net.

Cheers,
Corentin

PS: please let me know is you can't see the accented characters in
this email, i'll send you another version with pictures.
