Hmm, I guess you could do this:
QDataStream.writeString(obj)
# writes a QByteArray if given bytes or bytearray in Python 3,
# or a str in Python 2
# writes a QString if given a str in Python 3 or a unicode in
# Python 2
QDataStream.readString() -> obj
# returns a bytes in Python 3 or a str in Python 2 if a
# QByteArray was written
# returns a str in Python 3 or a unicode in Python 2 if a
# QString was written
I should think it would be straightforward to implement... not
particularly nice to document or use though?
