title: Obfuscation of variable names with whitespaces
body: <p><img src="https://i.stack.imgur.com/mSkjL.png" width="22" height="22" /> 
  My goal is not to use it in a real website, it's for knowledge and fun.</p>
  
  <p>I want to write something like :</p>
  
  <pre><code>var  =3;
  alert( );
  </code></pre>
  
  <p>(not with the space but with a specific unicode character)</p>
  
  <p>Is it possible? And if not, is there something equivalent?</p>
