python jsonify dictionary in utf-8

I want to get json data into utf-8

I have a list my_list = []

and then many appends unicode values to the list like this

my_list.append(u'ტესტ')return jsonify(result=my_list)

and it gets

{"result": ["\u10e2\u10d4\u10e1\u10e2","\u10e2\u10dd\u10db\u10d0\u10e8\u10d5\u10d8\u10da\u10d8"]}
