title: Why Julia returns "\uf8ff" when I use  (Apple logo) unicode?
body: <p>I thought Julia supports raw unicode input, such as:</p>
  
  <pre><code>julia&gt; test = "π£¢∞§"
  "π£¢∞§"
  
  julia&gt;  = 1 ;
  
  julia&gt; print( )
  1
  </code></pre>
  
  <p>However, it seems julia does not support  (Apple logo).</p>
  
  <pre><code>julia&gt;  = 123
  ERROR: syntax: invalid character ""
  
  julia&gt; test = ""
  "\uf8ff"
  </code></pre>
  
  <p>I wonder what's the underlying reason for that, and whether there is a way I can use  character in Julia?</p>
