Description:
------------
The example string given at the php simple xml manual page contains actór (spanish stress on the "o"). simplexml_load_string or even simplexml_load_file both fail. If I remove the ó it works fine.

Reproduce code:
---------------
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<movies>
 <movie>
  <title>PHP: Behind the Parser</title>
  <characters>
   <character>
    <name>Ms. Coder</name>
    <actor>Onlivia Actora</actor>
   </character>
   <character>
    <name>Mr. Coder</name>
    <actor>El Actor</actor>
   </character>
  </characters>

   So, this language. It's like, a programming language. Or is it a
   scripting language? All is revealed in this thrilling horror spoof
   of a documentary.

XML;

$xml = simplexml_load_string($xmlstr);
var_dump($xml);

Expected result:

var_dump should return a simplexml object

Actual result:
--------------
$xml is bool(false)
