Python Error; UnicodeEncodeError: 'ascii' codec can't encode character u'\u2026'

I am trying to extract some data from a JSON file which contains tweets and write it to a csv. The file contains all kinds of characters, I'm guessing this is why i get this error message:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2026'

I guess I have to convert the output to utf-8 before writing the csv file, but I have not been able to do that. I have found similar questions here on stackoverflow, but not I've not been able to adapt the solutions to my problem (I should add that I am not really familiar with python. I'm a social scientist, not a programmer)

import csv
import json

fieldnames = ['id', 'text']

with open('MY_SOURCE_FILE', 'r') as f, open('MY_OUTPUT', 'a') as out:

    writer = csv.DictWriter(
                    out, fieldnames=fieldnames, delimiter=',', quoting=csv.QUOTE_ALL)

    for line in f:
        tweet = json.loads(line)
        user = tweet['user']
        output = {
            'text': tweet['text'],
            'id': tweet['id'],
        }
        writer.writerow(output)

You just need to encode the text to utf-8:

for line in f:
    tweet = json.loads(line)
    user = tweet['user']
    output = {
        'text': tweet['text'].encode("utf-8"),
        'id': tweet['id'],
    }
    writer.writerow(output)

The csv module does not support writing unicode in python2:

Note This version of the csv module doesn’t support Unicode input. Also, there are currently some issues regarding ASCII NUL characters. Accordingly, all input should be UTF-8 or printable ASCII to be safe; see the examples in section Examples.
