title: How to convert string into unicode/utf for passing in a url?
body: <p>My string is:</p>
  
  <p><code>ĐT70, Châu Linh, Tùng Ảnh, Đức Thọ, Hà Tĩnh, Vietnam.</code></p>
  
  <p>While passing this text in a url query string, it is coming as:</p>
  
  <p><code>ĐT70%2C+Châu+Linh%2C+Tùng+Ảnh%2C+Đức+Thọ%2C+Hà+Tĩnh%2C+Vietnam.</code></p>
  
  <p>But I want it in this format:</p>
  
  <pre><code>\U0111\U01b0\U1eddng \U0110\U1eadp, Th\U00f4ng T\U1ef1, T\U00f9ng \U1ea2nh, \U0110\U1ee9c Th\U1ecd, H\U00e0 T\U0129nh, Vietnam.
  </code></pre>
  
  <p>How could I get that string in this format? Please answer.</p>
