>>> r = HttpResponse()
If we insert a unicode value it will be converted to an ascii
string. This makes sure we comply with the HTTP specifications.
>>> r['value'] = u'test value'
>>> isinstance(r['value'], str)
True
An error is raised When a unicode object with non-ascii is assigned.

Traceback (most recent call last):

UnicodeEncodeError: ..., HTTP response headers must be in US-ASCII format
The response also converts unicode keys to strings.
>>> r[u'test'] = 'testing key'
>>> l = list(r.items())
>>> l.sort()

It will also raise errors for keys with non-ascii data.
