19081	Non-ASCII query string aren't decoded properly	Aymeric Augustin	Aymeric Augustin	"In [fcc8de05] I enabled `unicode_literals` in `django.core.servers.basehttp`.

This turns `environ['QUERY_STRING']` into a unicode string, which later on prevents correct decoding in `QueryDict`.

Basically the fix is:

An audit of this module seems necessary. It may even be extended to `django.core.servers`."	Bug	new	HTTP handling	dev	Release blocker				Accepted	1	0	1	0	0	0
