But you can use other seperators as well. To check which lines are causing the issue you can try something like this: def is_not_ascii (string): return string is not None and any ( [ord (s) >= 128 for s in string]) df [df [col].apply (is_not_ascii)] You'll need to specify the column col you are testing.
