title: How do you mark strings as "Safe" in a view (or the template) in Jinja2?
body: <p>Typically when you want to mark string output as safe in Jinja2 you do something like this:</p>
  
  <pre><code>{{ output_string|safe() }}
  </code></pre>
  
  <p>However, what if output_string is <em>always</em> safe? I don't want to repeat myself every time by using the safe filter.</p>
  
  <p>I have a custom filter called "emailize" that preps urls for output in an email. The ampersands always seem to become escaped. Is there a way in my custom filter to mark the output as safe?</p>
