     - added new flag to String and create_engine(), assert_unicode=(True|False|None).
-    When convert_unicode=True, this flag also defaults to `True`, and results in all 
-    unicode conversion operations raising an exception when a non-unicode bytestring
-    is passed as a bind parameter.  It is strongly advised that all unicode-aware
