Hmmm, using string I/O when one really wants to do binary I/O gives me a bad feeling. Haskell characters are defined to be Unicode characters, so the above only works because current Haskell implementations usually get this wrong (either no Unicode support at all and/or ignoring any encodings and doing I/O only with the lower 8 bits of the characters)... hGetBuf/hPutBuf plus their non-blocking variants are the only way to *really* do binary I/O currently.
