In Python 3.11 CSV files are allowed to have null characters so the test data is no longer a valid. We update it to not have a valid unicode character to still test this code path correctly. I'm not concerned about the fact that the files with null will get past this test beacause there are other checks on the content of the file that catch if it doesn't have enough or the right fields so this should be a safe change to make to the tests.
