UnicodeEncodeError model field returns unicode and not UTF-8

[GoogleCodeExporter]

What steps will reproduce the problem?

1. use wad serializer in Py2.7 and Dj1.3, serializing model with e.g. field 
'name' which has value that is beyond ascii (e.g. name = u'täst'), have 
ensure_ascii=False

2. When serializing (ensure_ascii=False) you then get 'ascii' codec can't 
encode characters in position 9-10: ordinal not in range(128) in self.end and 
doing simplejson.dump

3. poof...

What is the expected output? 
Was expecting to see field correctly encoded in json string in UTF-8. u'täst' 
should be 't\xc3\xa4st'

What do you see instead?
 It is a normal python unicode string e.g. u'täst' or u't\xe4st', this is not UTF-8 so the error is correct but wrong ;-)


What version of the product are you using? On what operating system? Mac 
10.7.2, Py2.7, Django 1.3

Please provide any additional information below.

Did set ensure_ascii to True, then it returns correctly but the resulting JSON 
shown has name=u't\xe4st', i.e. the string is not utf-8 encoded.
