title: How to handle invalid unicode with simplexml
body: <p>Simplexml fails with the following error message:</p>
  
  <pre><code>simplexml_load_file(): fooo.xml:299108: parser error : Char 0xFFFE out of allowed range
  </code></pre>
  
  <p>From my understanding, the complaint is about an invalid unicode character. Line 299108 doesn't have "FFFE", but it contains "EFBFBE". </p>
  
  <p>Is there way to handle this type of errors in simplexml?</p>
