title: Save unescaped HTML to string
body: <p>I have a string:</p>
  
  <pre><code>html = '&amp;lt;div class="blue"&amp;gt; &amp;lt;p&amp;gt;This is a description string'
  </code></pre>
  
  <p>If I do <code>&lt;%= html.html_safe %&gt;</code> in my view, it returns the proper string, but not if I do it in the console. If I do:</p>
  
  <pre><code>unencoded = html.html_safe
  puts unencoded 
  </code></pre>
  
  <p>it returns in console</p>
  
  <pre><code>&amp;lt;div class="blue"&amp;gt; &amp;lt;p&amp;gt;This is a description string
  </code></pre>
  
  <p>How do I decode the string so I can perform operations on the tags using Nokogiri?</p>
