Django utf-8 csv export
'''
Using the same example on Python 2.7 docs
'''
import csv, codecs, cStringIO
class UnicodeWriter:
"""
A CSV writer which will write rows to CSV file "f",
which is encoded in the given encoding.
"""
def __init__(self, f, dialect=csv.excel, encoding="utf-8", **kwds):
# Redirect output to a queue
self.queue = cStringIO.StringIO()

Here we combine Django example:

with UnicodeWriter class
'''
writer = UnicodeWriter(response)
writer.writerow(["Bar", "1", "2"])
return response
