Django: set_cookie со специальными символами не работает

Question

Я использую Django 1.11 с Python 3.4 и не могу сохранять куки со специальным символом.

Эта проблема возникает при сборке Django на сервере разработки, а также на моем производительном сервере Apache2.Поэтому я думаю, что эта проблема не связана с веб-сервером.

Пожалуйста, посмотрите ниже очень маленький пример с одним специальным символом из польского алфавита:

def test(request):
    response = HttpResponse("ERROR")
    response.set_cookie('br_last_name', 'ń')
    return respons

И это исключение, которое я получаю:

Traceback (most recent call last):
  File "/usr/lib/python3.4/wsgiref/handlers.py", line 138, in run
