title: Twig filters and quotes return
body: <p>I created simple Twig filter</p>
  
  <pre><code>class Twig_Extension_Form extends Twig_Extension{
  public function getName() {
      return 'Form';
  }
  
  public function getFilters() {
      return [
          'fLabel'=&gt;new Twig_Filter_Method($this,'label_filter')
      ];
  }
  
  public function getFunctions() {
      return [];
  }
  
  public function label_filter($string,$id=null,$class=null){
      return '&lt;label'.(!is_null($id)&amp;&amp;is_string($id)?' id="'.$id.'"':null).(!is_null($class)&amp;&amp;is_string($class)?' class="'.$class.'"':null).'&gt;'.$string.'&lt;/label&gt;';
  }}
  </code></pre>
  
  <p>Filter worked but when I display code in browser quotes are replace on entities. When I use echo instead return filter work fine.</p>
  
  <p>I want use return because not always label schould be display immediately.</p>
