When a JSON returns through the methods make_response(jsonify()), my browser can not understand the special characters, how to return JSON in UTF-8 encoding?

Follows the code:

@app.route('/', methods=['GET'])
def index():
    return make_response(jsonify(address_info('Rua Parianas, 665 São Paulo').to_json()), 201)

Answer I would like to receive:

{
  "city": "São Paulo", 
  "country": "Brazil", 
  "lat": -23.5100646, 
  "lng": -46.54488689999999, 
  "neighborhood": "Jardim Jaú (Zona Leste)", 
  "state": "SP", 
  "street_name": "Rua Parianas", 
  "street_number": "665"
}

Answer I’m getting:

{
  "city": "S\u00e3o Paulo", 
  "country": "Brazil", 
  "lat": -23.5100646, 
  "lng": -46.54488689999999, 
  "neighborhood": "Jardim Ja\u00fa (Zona Leste)", 
  "state": "SP", 
  "street_name": "Rua Parianas", 
  "street_number": "665"
}

The answer to the JSON file is perfectly ok! Special characters are encoded this way for compatibility and security reasons; because of html Escaping (which can bring vulnerabilities to the system) and code page. (In China BIG5 is used, and in Japan SJIS instead of UTF-8 for example..)

When picking up JSON data just treat it the right way, using JSON library or Python codecs to decode it.
