def getstate(self):
return (b"<STR_LIT>", <NUM_LIT:0>)<EOL>
Return the current state of the decoder.

This must be a (buffered_input, additional_state_info) tuple.
buffered_input must be a bytes object containing bytes that
were passed to decode() that have not yet been converted.
additional_state_info must be a non-negative integer
representing the state of the decoder WITHOUT yet having
processed the contents of buffered_input.  In the initial state
and after reset(), getstate() must return (b"", 0).
