DomDocument and special characters

Question

This is my code:

$oDom = new DOMDocument();
$oDom->loadHTML(\"èàéìòù\");
echo $oDom->saveHTML();

This is the output:

Answer 1

$dom = new DomDocument();
$str = htmlentities($str);
$dom->loadHTML(utf8_decode($str));
$dom->encoding = 'utf-8';
.
.
.
$str = $dom->saveHTML();
$str = html_entity_decode($str);

The above code worked for me.
