get this error when reading it into a Pandas dataframe. If I copy the data into a fresh text file (temp.csv) and save that it works fine! The two text files are clearly different (one is 74 bytes the other is 150) - invisible characters perhaps? - but it's very annoying as I want the python code to load the text files produced by the C code.

I am unsure of the exact issue but I have narrowed it down to a single row which I have pickled and uploaded it to dropbox. If you obtain the pickle try the following: df = pd.read_pickle('faulty_row.pkl') df.to_csv('faulty_row.csv', error tokenizing data. encoding='utf8', index=False) df.read_csv('faulty_row.csv', encoding='utf8') I get the following exception: CParserError: Error tokenizing data. C error: Buffer overflow caught - possible malformed input file. If you try and read the CSV using the python engine then no exception is thrown: df.read_csv('faulty_row.csv', encoding='utf8', engine='python') Suggesting that the issue is with read_csv and not to_csv.
