title: Dealing with special character in Nokogiri / Regex
body: <p>I am getting the text from the body of an HTML doc as below. When I try to regex scan for the term "Exhibit 99", I get an no matched, i.e, an empty array. However, in the html, I do see "Exhibit 99", although inspect element shows it with &amp;nbsp99. How can I get rid of these HTML characters and search for "Exhibit 99" as if it were a regular string?</p>

  doc = Nokogiri::HTML(open(url))
  body = doc.css("body").text
  body.scan(/exhibit 99/i)
  </code></pre>
