title: How do I encode/decode HTML entities in Ruby?
body: <p>I am trying to decode some HTML entities, such as <code>'&amp;amp;lt;'</code> becoming <code>'&lt;'</code>.</p>
  
  <p>I have an old gem (<a href="http://github.com/tma/html_helpers/" rel="noreferrer">html_helpers</a>) but it seems to have been abandoned twice.</p>
  
  <p>Any recommendations? I will need to use it in a model.</p>
