[issue4847] csv fails when file is opened in binary mode

[Skip Montanaro]

Skip Montanaro <skip at pobox.com> added the comment:

This issue seems to have simply been overlooked when 3.0 was released.
It should be fixed in the next round of 3.0 and 3.1 updates.  Any
feeback on the idea that the csv.reader constructor (and probably the
DictReader and proposed NamedTupleReader constructors) should take an
optional encoding argument?  In fact, the writers should as well
which would inform the writer how to encode the output when writing.
