Can't use writeFile to write unicode characters.

I tried to the "locale" environmental variables to "en_US.utf8", but still I cannot write unicode characters.

source:

main = do
    hSetEncoding stdout utf8
    putStrLn "αρχίδια"
    writeFile "hello.txt" "σκατούλες"

output:

αρχίδια
commitBuffer: invalid argument (Illegal byte sequence)

without manually hSetEncoding stdin, putStrLn also fails with the same error message.

From what I was told on #haskell, on linux ghc uses setlocale to figure out what encoding to use, but this is not present in OpenBSD.

Simply making those functions read $LANG (I think) would solve this for OpenBSD, but I might be wrong.

What exactly do you mean by 'the "locale" environmental variables'?

Also, do you have a "locale" program? If so, what is the output when you run it?

I meant LANG and LC_ALL, etc.

There's no locale program. Only a setlocale(3) function.. http://www.openbsd.org/cgi-bin/man.cgi?query=setlocale&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html

Usually, applications (for example tmux, mutt, etc.) that may need to output unicode characters, understand the locale by reading those enviromental variables I mentioned above. I thought it would work like that with haskell, but I was wrong.

Let me know if you need anything else.

Thanks!

Can anyone on OpenBSD confirm this is still a problem with GHC 7.8.3?
