Which is unfortunate, because of the requirement to pass a Ptr. We
really need "hPutBytes :: [Word8] -> IO ()" etc.

Also, changing the existing functions to deal with encodings is likely
to break a lot of things (i.e. anything which reads or writes data
which is in neither UTF-8 nor the locale-specified encoding).
