GHC mangles UTF by default. You probably want to use one of the utf8 packages; eg. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/utf8-string or http://hackage.haskell.org/cgi-bin/hackage-scripts/package/utf8-light
(Neither of them seems to allow for accessing *arguments* rather than stdin/stdout, but you could probably do something with the encoding/decoding functions.)
in order to get proper unicode handling, one should ask win api directly for cmdline: myGetArgs = do alloca $ \p_argc -> do p_argv_w <- commandLineToArgvW getCommandLineW p_argc argc <- peek p_argc argv_w <- peekArray (i argc) p_argv_w mapM peekTString argv_w >>== tail foreign import stdcall unsafe "windows.h GetCommandLineW" getCommandLineW :: LPTSTR foreign import stdcall unsafe "windows.h CommandLineToArgvW" commandLineToArgvW :: LPCWSTR -> Ptr CInt -> IO (Ptr LPWSTR) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
