QueryDict processes some Unicode symbols incorrectly

Description

Using Django 1.8 I get strange result feeding QueryDict a string which contains Unicode U+00AB symbol. More concrete, first of two bytes is omitted.
Other randomly taken symbols are parsed correctly.

double_angle="value=%C2%AB" # «
yo="value=%D1%91" # ё
katakana="value=%E3%82%A1" # ァ

for qs in (double_angle, yo, katakana):
    dct=QueryDict(query_string=qs, encoding=None)
    print("%s -> %s" % (qs, dct))

Output:

value=%C2%AB -> <QueryDict: {u'value': [u'\xab']}>
value=%D1%91 -> <QueryDict: {u'value': [u'\u0451']}>
value=%E3%82%A1 -> <QueryDict: {u'value': [u'\u30a1']}>

On Django master with Python 3 (Python 2 is no longer supported there), the output is:

value=%C2%AB -> <QueryDict: {'value': ['«']}>
value=%D1%91 -> <QueryDict: {'value': ['ё']}>
value=%E3%82%A1 -> <QueryDict: {'value': ['ァ']}>

It looks like that's correct behavior? If so, we can most likely close the issue. Per our supported versions policy, 1.8 is only receiving security and data loss fixes.

Ok, we'll move on to newer Django release
