I would like to escape a file, which I'm including
following code won't escape the html tags in file "_custom_plugin_script.html.twig". Is there another way?
<pre>
    {% autoescape true %}
        {% include "_custom_plugin_script.html.twig" | raw %}
    {% endautoescape %}
</pre>
After a couple days, I have found a workaround, but not an answer. So first raw would not escape therefore I should use escape. However raw and escape won't work within {% %} but in {{}}.
So here comes the workaround
Content of the Action
$customPluginScript = $app['twig']->render('_custom_plugin_script.html.twig', array(
    'data' => $data,
));
return $app['twig']->render('confirm.html.twig', array(
    'data' => $data,
    'customPluginScript' => $customPluginScript
));
And the a part of confirm.html.twig
<script>
// don't escape content of customPluginScript
  {{ customPluginScript | raw }}
</script>
<!-- escape content of customPluginScript -->
<pre>
  {{ customPluginScript }}
</pre>
