title: Data of json request with strange characters in volley request
body: <p>I am making a Json request and I get the data and place it in a list view but some of the strings i get have accents or 'ç' and it doesn't appear correctly.
  For example, the string is 'Bragança' and i receive 'BraganÃ§a' or 'à' and get 'Ã'. If i do the request in the browser, all works properly.
  My request.</p>
