Since it was a byte string sent to the database and a Unicode string
coming back, the solution would be to .decode() the byte string.
However, I doubt that's the issue; that's being done for you
implicitly by the lower-level connections. Also, in Python 2:

>>> u'testbh3' ==  'testbh3'
True

So that's not your primary problem. You could try that, but I doubt
it'll solve anything for you.

Are you able to switch to Python 3, though? If you are, Unicode issues
tend to be a lot easier to resolve there.
