[issue39876] csv.DictReader.fieldnames interprets unicode as ascii

[Andreas Spar]

New submission from Andreas Spar <andreas.spar at gmx.de>:

with open(filename, "rt") as csvfile:
        csv_reader = csv.DictReader(csvfile, delimiter=csv_delimiter)
        filednames = csv_reader.fieldnames

In Python 3.8 csv expects utf-8 encoded files but apperently doens't read the header with utf-8 format.
If the csv file has an header named 'Französisch' it will be saved as 'Französisch'.
