[issue1606092] csv module broken for unicode [In reply to]

Craig McQueen <ces-pub [at] mcqueen> added the comment:

Is this still an open bug? I have the following code:

lookup = {}
csv_reader = csv.reader(codecs.open(lookup_file_name, 'r', 'utf-8'))
for row in csv_reader:
lookup[row[1]] = row[0]

And it "appears to work" (it runs) using Python 2.6.2. So has this bug
been fixed?

Craig McQueen <ces-pub [at] mcqueen> added the comment:

I think I see now--it accepts Unicode input, but converts it back to
bytes internally using the ASCII codec. So it works as long as the
Unicode input contains on ASCII characters. That's a gotcha.

It appears that it's been fixed in Python 3.x, judging by the documentation.

----------
versions: +Python 2.4, Python 2.5, Python 2.6, Python 2.7

R. David Murray <rdmurray [at] bitdance> added the comment:

This is indeed fixed in Python 3. If someone wishes to step forward
with patches for 2.7, they can reopen this bug, but I don't think it is
worth the effort.
