+The tests will create and drop tables t1 and t2 as necessary.
 
 These tests use the pyodbc library from the build directory, not the version installed in your
 Python directories.  You must run `python setup.py build` before running these tests.

+
+Note: Include charset=utf8mb4 in the connection string so the high-Unicode tests won't fail.
