readFile :: FilePath -> IO String works fine for me, also when reading binary files. But yes, maybe there should be a function returning IO Word8. Obviously, the implementation of readFile automatically converts from Word8 to Char and it is not only a type cast because Char has 16 bits. > >I found out that fromIntegral does the conversion from Word8 to Char > >but I do not know how to convert from Char to Word8. > > I think fromIntegral will work for that too. No, there is no suitable instance. However, it works like this: map (toEnum . fromEnum) . Bzip2.decompress . map (toEnum . fromEnum) Michael _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
