title: Correctly Handle UTF-8 In JSON on iOS
body: <p>I'm receiving some JSON that has weird UTF-8 strings. Eg:</p>
  
  <pre><code>{
    "title": "It\U2019s The End";
  }
  </code></pre>
  
  <p>What's the best way to handle this data so that it can be presented in a readable way? I'd like to convert that \U2019 into the quote mark that it should represent.</p>
  
  <p>Edit:
  Assume I have parsed the string into a NSString* <code>jsonResult</code></p>
  
  <p>Edit 2: I'm receiving the JSON through <a href="https://github.com/AFNetworking/AFNetworking" rel="noreferrer">AFNetworking</a>:</p>
  
  <pre><code>AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
      NSString* jsonResult = [JSON valueForKeyPath:@"title"];
  } failure:nil];
  </code></pre>
