I agree that it is purely an encoding issue. In PHP, this is how I solved this problem:

1. Before passing the html-fragment to SimpleXMLElement constructor I decoded it by using html_entity_decode.

$headerDoc = '' . utf8_encode(html_entity_decode($headerFragment)) . ''; 
$xmlHeader = new SimpleXMLElement($headerDoc);

Now the above code does not throw any undefined entity errors.
