title: How to add non-escaped ampersands to HTML with Nokogiri::XML::Builder
body: <p>I would like to add things like bullet points "&#8226;" to HTML using the XML Builder in Nokogiri, but everything is being escaped.  How do I prevent it from being escaped?</p>
  
  <p>I would like the result to be: </p>
  
  <pre><code>&lt;span&gt;&amp;#8226;&lt;/span&gt; 
  </code></pre>
  
  <p>rather than:</p>
  
  <pre><code>&lt;span&gt;&amp;amp;#8226;&lt;/span&gt; 
  </code></pre>
  
  <p>I'm just doing this: </p>
  
  <pre><code>xml.span { 
    xml.text "&amp;#8226;\ " 
  }
  </code></pre>
  
  <p>What am I missing? </p>
