title: SyntaxError: Invalid character '\u8203'
body: <p>This function gives me the following error:</p>
  
  <blockquote>
    <p>SyntaxError: Invalid character '\u8203'</p>
  </blockquote>
  
  <p>All looks good to me,</p>
  
  <pre><code>function changeColumnWidth() {
      var w = Math.random() * 200+80;
      $('#menu').css("width", w+"px");
  }​
  </code></pre>
  
  <p>can someone spot the error?</p>
