Weird characters in json, when using get method from url

Question

RestTemplate restTemplate = new RestTemplate(); 
String response = restTemplate.getForObject(link, String.class);
JSONObject json = (JSONObject) new JSONParser().parse(response);

json in url: {"description": "Explains how to construct 45° and 90°"}

json I'm getting: {"description": "Explains how to construct 45° and 90°"}

any help to get actual json, without weird characters is apreciated.
