title: Entity 'acirc' not defined from simplexml_load_string
body: <p>So I have a PHP Script thats parsing an XML Response from Google Analytics. It has been working for a few weeks, but today I've been getting this warning, and simple xml load string is not converting the xml response into a simplexml object.</p>
  
  <blockquote>
    <p>Message:  simplexml_load_string():
    Entity: line 743: parser error :
    Entity 'acirc' not defined</p>
  </blockquote>
  
  <p>I have tried utf8_encoding the response before I pass it into simplexml_load_string, but it isn't working. I believe that acirc is an encoded symbol, and that this symbol is screwing up the parser somehow?</p>
  
  <p>I get the warning above twice, and then I get this one twice also:</p>
  
  <blockquote>
    <p>Message:  simplexml_load_string():
    Entity: line 743: parser error :
    Entity 'cent' not defined</p>
  </blockquote>
  
  <p>Any advice would be a huge help, thanks!</p>
  
  <p>Thanks for the comment Marc, I have tried this:</p>
  
  <pre><code>$xml = simplexml_load_string(htmlspecialchars_decode($response_body));
  </code></pre>
  
  <p>And I get an interesting error, but the xml object is still empty:</p>
  
  <blockquote>
    <p>Entity: line 743: parser error : Input
    is not proper UTF-8, indicate encoding
    ! Bytes: 0x84 0x26 0x63 0x65</p>
