  <p>and converting it from below code:</p>
  
  <pre><code>$encoded_string = bin2hex(mb_convert_encoding($str, "UTF-16BE", 'UTF-8'));
  </code></pre>
  
  <p><strong>Output at Mobile Device :</strong></p>
  
  <p><strong>इन रिकॉ‌(Here Zero-Width Non-Joiner is displaying in output)र्ड्स पर है सलमान की नजर, धूम-3 को पछाड़ेगी जय हो?</strong></p>
