title: put special character by code in yaml file
body: <p>Working with Symfony 2 and Sonata Admin Bundle. Refactored translation from xliff to yml. There is a home sign <code>⌂</code> in translation file which was saved as <code>&amp;#8962;</code> in xliff file.</p>
  
  <p>I can save it as unicode symbol but I cannot find a way to save it as code as it was done in xliff. Tried:</p>
  
  <pre><code> breadcrumb.link_dashboard: &amp;#8962;
   breadcrumb.link_dashboard: "&amp;#8962;"
   breadcrumb.link_dashboard: '&amp;#8962;'
   breadcrumb.link_dashboard: \&amp;#8962;
   breadcrumb.link_dashboard: \u&amp;#8962;
   breadcrumb.link_dashboard: \u#8962
   breadcrumb.link_dashboard: \x#8962
   breadcrumb.link_dashboard: \u8962
   breadcrumb.link_dashboard: \x8962
  </code></pre>
  
  <p>Google does not help either.</p>
