Are you missing anything? Perhaps those bytes, when printed in your
terminal's encoding, *are* garbage. Are you expecting them to be
encoded text, or something else?

You have successfully done that. What else do you want to do with
those bytes once read?
Perhaps a better question: What goal are you trying to accomplish?
