How can I use mongoengine.to_json() method with utf8 encoding

Question

I have a code like this:

 import ast 
 objects = MenuModel.objects()
 data = ast.literal_eval(objects.to_json())

this code return :

    {
        "_id": {
            "$oid": "54eab211b0b7080827f3b9d3"
        }, 
        "name": "\\u0627\\u06cc\\u0646\\u0645 \\u06cc\\u0647 \\u06cc\\u0648\\u0646\\u06cc \\u06a9\\u062f", 
    }

and i can't return unicode data. How can i convert "name" filed to unicode?

why do you call ast.literal_eval() (that expects a Python literal as an input) on JSON data (as the name .to_json() implies)? — jfs

>>> import json
>>> json_text = json.dumps(u'\N{ARABIC LETTER ALEF}')
>>> json_text
'"\\u0627"'
>>> #XXX WRONG DO NOT DO IT!!!
>>> import ast; ast.literal_eval(json_text)
'\\u0627'

Do this instead if you need to convert a json text into Python object:

>>> json.loads(json_text)
u'\u0627'

Or avoid calling .to_json() and work with objects object directly (convert it to a dict if necessary).
