Getting SimpleXMLElement to include the encoding in output

PHP :

$xml = new SimpleXMLElement("<Title0></Title0>");
$xml->Title1='Some Text  1';
$output = $xml->asXML('mak.xml');

XML Output :

<?xml version="1.0"?>  
<Title0>
    <Title1>Some Text 1</Title1>
</Title0>

But I want to add attrbute like encoding="utf-8" to xml header , so that I can have something like this :

<?xml version="1.0" encoding="utf-8" ?>  
<Title0>
    <Title1>Some Text 1</Title1>
</Title0>

I dont want to use find and replace sort of things on the output file.
