Error when using Python 3 + Unicode.
Only pickle protocol version 0 and 1 can accurately convert the data to
a string, because the storage we use the "Text" type field. I was the
reason that the data is simply not saved to the database, without any errors.
In Python 3 pickle.dumps function protocol version installed by default 3.
Therefore calls pickle.dumps() to explicitly specify the protocol version 0.
This was done.
