Comment gérer les caractères non ascii de CSV lors de l'utilisation de json.loads en Python ?

J'ai regardé quelques réponses, y compris celle-ci, mais aucune ne semble répondre à ma question.

Voici quelques exemples de lignes de CSV :

_id category
ObjectId(56266da778d34fdc048b470b)  [{"group":"Home","id":"53cea0be763f4a6f4a8b459e","name":"Cleaning Services","name_singular":"Cleaning Service"}]
ObjectId(56266e0c78d34f22058b46de)  [{"group":"Local","id":"5637a1b178d34f20158b464f","name":"Balloon Dí©cor","name_singular":"Balloon Dí©cor"}]

Voici mon code :

import csv
import sys

from sys import argv
import json


def ReadCSV(csvfile):
with open('newCSVFile.csv','wb') as g:
    filewriter = csv.writer(g) #, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)

    with open(csvfile, 'rb') as f:
        reader = csv.reader(f) # ceate reader object
        next(reader) # skip first row

        for row in reader: #go trhough all the rows
            listForExport = [] #initialize list that will have two items: id and list of categories

            # ID section
            vendorId = str(row[0]) #pull the raw vendor id out of the first column of the csv
            vendorId = vendorId[9:33] # slice to remove objectdId lable and parenthases
            listForExport.append(vendorId) #add evendor ID to first item in list


            # categories section
            tempCatList = []  #temporarly list of categories for scond item in listForExport

            #this is line 41 where the error stems
            categories = json.loads(row[1]) #create's a dict with the categoreis from a given row

            for names in categories:  # loop through the categorie names using the key 'name'

                print names['name']

Voici ce que j'obtiens :

Cleaning Services
Traceback (most recent call last):
  File "csvtesting.py", line 57, in <module>
    ReadCSV(csvfile)
  File "csvtesting.py", line 41, in ReadCSV
    categories = json.loads(row[1]) #create's a dict with the categoreis from a given row
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 9-10: invalid continuation byte

Ainsi, le code extrait la première catégorie Cleaning Services, mais échoue lorsque nous arrivons aux caractères non ascii.

Comment puis-je gérer cela? Je suis heureux de simplement supprimer tous les éléments non ASCII.
