title: Mako escaping issue within Pyramid
body: <p>I need to put javascript function to mako template. The first argument of this function is string, so I write in my *.mako file (dict(field_name='geom')):</p>
  
  <pre><code>init_map(
      '${field_name}'
  );
  </code></pre>
  
  <p>But when I see my html page it loks like:</p>
  
  <pre><code>init_map(
      &amp;#39;geom&amp;#39;
  )
  </code></pre>
  
  <p>How I can disable escaping in this case?</p>
  
  <p>Rendering performs the following way:</p>
  
  <pre><code>from pyramid.renderers import render
  render('georenderer/map.mako', template_args)
  </code></pre>
