title: Twig truncate with read more link
body: <p>I want to use the truncate filter of Twig. And it works fine.</p>
  <p>I wanted to use as a third argument a link to read more about the article. But it does not work.</p>
  <p>Here is the code:</p>
  <pre><code>{% set read_more_link %}
        &lt;a href=&quot;{{ path('course_news_show', {news: entry.id}) }}&quot;&gt;... read more&lt;/a&gt;
  {% endset %}
  
  &lt;p&gt;{{ entry.description|truncate(150, true, &quot;read_more_link&quot;) }}&lt;/p&gt;
  </code></pre>
  <p>What comes out is this:</p>
  <pre><code>&quot;Lorem ipsum dolor sit met, &lt;a href=&quot;/course/news/44&quot;&gt;... read more &lt;/a&gt;&quot;
                                  
  </code></pre>
  <p>So, the link is displayed as text in the <code>&lt;p&gt;</code>. How can I solve this problem?</p>
