Test Client response.json() UnicodeDecodeError

[Daniel Blasco]

Hi,

I'm testing the REST API of my application and I found an error that I think that's a Django's issue.

I'm using:

• Django==1.9.4
  
• djangorestframework==3.3.3

I have set the rest framework setting UNICODE_JSON to True.

When i'm testing a JSON response that contains a special character like 'á' then I get a UnicodeDecodeError. This is the traceback:

Traceback (most recent call last):

  File ".../tests/assets/test_views.py", line 584, in test_get

    response.json()

  File ".../lib/python2.7/site-packages/django/utils/functional.py", line 13, in _curried

    return _curried_func(*(args + moreargs), **dict(kwargs, **morekwargs))

  File ".../lib/python2.7/site-packages/django/test/client.py", line 662, in _parse_json

    return json.loads(response.content.decode(), **extra)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 268: ordinal not in range(128)

If I change the line 662 in django/test/client.py to:

return json.loads(response.content.decode(response.charset), **extra)

then it works fine. In this case response.charset is utf-8.

Thanks,

Daniel

Looks reasonable, although I am not entirely clear what role charset has in a JsonResponse. See https://code.djangoproject.com/ticket/23949.

Running into the same issue - charset isn't correct, I think it ought to be hardcoded to `utf-8`.
