title: Rails: html_escape isn't working
body: <p>For some reason html escaping isn't working in my Rails application. Even if I write something like </p>
  
  <pre><code>&lt;%=h '©äö' %&gt; 
  </code></pre>
  
  <p>it isn't converting any of the characters to HTML entities.</p>
  
  <p>I have no clue what the could be. It worked always fine and now just suddenly it don't.</p>
  
  <p>Any ideas?</p>
