title: Twig doesn't show String with blank spaces
body: <p>I have a problem with Twig.</p>
  
  <p>I have an object that contains one attribute whose type is a String. The String contains some blank spaces  " ",(example "Prueba Primera"), but in the twig view when I show the text the view shows only "Prueba" the other part of the string doesn´t show. 
  This is my object in php:</p>
  
  <pre><code>$informe-&gt;setTitulo("Prueba Primera");
  </code></pre>
  
  <p>This is my code in twig:</p>
  
  <pre><code>&lt;input type = "text" name = "titulo"  id = "titulo" class = "texto"   value = {{informe.titulo}} disabled/&gt;
  </code></pre>
  
  <p>And twig shows only : "Prueba"</p>
