title: NSData to NSString with JSON response
body: <p><strong>NSData* jsonData</strong> is the http response contains JSON data.</p>
  
  <pre><code>NSString* jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
  NSLog(@"jsonString: %@", jsonString);
  </code></pre>
  
  <p>I got the result:</p>
  
  <pre><code>{ "result": "\u8aaa" }
  </code></pre>
  
  <p>What is the proper way to encoding the data to the correct string, not unicode string like "\uxxxx"?</p>
