title: laravel regex validation not working
body: <p>I've just started using laravel and I'm working on validating a textarea in one of my forms.</p>
  
  <p>The textarea is for the users bio and so I only want to allow letters, numbers, spaces and the following characters: 
  , . ? ; : ' " - () ! / @ $ </p>
  
  <p>This is what I have</p>
  
  <pre><code>$validator = Validator::make(Input::all(),
  array('bio' =&gt; array('regex:[a-zA-Z0-9 ,\.\?;:\'"-\(\)!/@\$]')
      )
  );
  </code></pre>
  
  <p>I've been searching and trying a lot to get it to work but I just can't figure it out.</p>
  
  <p>Any help would be much appreciated.</p>
  
  <p>Thanks</p>
