title: json decode for special characters
body: <p>I have a string <code>test  éàå</code>. when I am performing a json_encode, the special character is being converted to <code>test  u00e9u00e0u00e5</code>.</p>
  
  <p>Now when performing a json_decode, I am not getting back the original characters but instead it is remaining as <code>test  u00e9u00e0u00e5</code></p>
  
  <p>Can someone help me to have the special character back.</p>
