Please advise how to write Unicode string, so this example would work:
main = do putStrLn "Les signes orthographiques inclus les accents (aigus, grâve, circonflexe), le tréma, l'apostrophe, la cédille, le trait d'union et la majuscule." (...)
Besides the Haskell stuff, you probably want to check if your terminal outputs utf-8. I use a nice X terminal named 'mlterm'. It's main goal is to support unicode. But I don't know enough to tell you how to check your terminal, or even if just changing to mlterm will always work. Sometimes, I wonder why distributions don't just agree on considering support for anything but utf-8 a bug (except in 'iconv', of course). Well, there's probably someone out there who would have problems with that, and I don't want problems for anyone. But I hope their problems would be worst than mine trying to deal with different encodings. Best, Maurício
