[Haskell-beginners] Encoding strings

[legajid]

Hi,

i experiment problems writing files.
Reading an access 97 database and displaying data in a wxhaskell grid, 
everything is correct.
When i write data in a text file, some characters are translated : "é" 
becomes \233.

How to correct this ?
I looked for hSetEncoding but didn't find it in System.IO, nor in 
GHC.IO.Handle that doesn't exist on my system.
I tried hSetBinaryMode, without success.

If this helps, I run ghc 6.10.4 on windows XP.

Thanks for an idea,
Didier.
