title: Ajax call response as question mark instead of Arabic characters
body: <p>I am making a ajax call POST request(sending audio as a blob) to the server. I am expecting Arabic characters as response but I am getting question mark instead.</p>
  <pre><code>$.ajax({
          &quot;async&quot;:true,
          &quot;url&quot;: url,
          &quot;method&quot;:&quot;POST&quot;,
          &quot;contentType&quot;: false,
          &quot;processData&quot;: false,
          &quot;data&quot;:data_audio,
          success:function(response){}
  </code></pre>
  <p>Response is coming as - {result: &quot;?????.&quot;, status: &quot;success&quot;}</p>
