It should be implemented. It may be a little tricky if there's codec
state, but I'm okay with raising an exception in that case or doing
something else that's sensible.

This should be done with a new function, not added to print. Once you
specify an encoding, you have to write to sys.stdout.buffer, which is
the underlying binary stream; but you'd have to flush the
TextIOWrapper and deal with incomplete codec state, and in general I
don't think it's a good idea.
