[DB-SIG] PEP 249 .Binary() function incorrect for Python 3.0 ?

[Vernon Cole]

Marc-Andre;
  So, to clarify:  You are saying that it is acceptable for a Python 3.0
implementation
to raise an error when .Binary() receives a unicode string.  It should
expect a b'xxx binary string here xxx' type.
  Is that correct?
