php DOMDocument - manipulating and encoding

Question

$dom = new DOMDocument('1.0', 'UTF-8');
$dom->loadHTML($content);
$divs = $dom->getElementsByTagName("div");
foreach ( $divs as $div ) {
    if ( $class = $div->attributes->getNamedItem("class") ) {
        if ( $class->nodeValue == "simplegalleryholder" ) 
            $div->parentNode->removeChild( $div );
    }
}
$content = $dom->saveHTML();

This simple code should help me with removing

<div class="simplegalleryholder"> .... </div>

from the document. The only problem is, that $content contains utf8 encoded special characters (ąęść etc), that are destroyed by proces (i get iÄ™ Å‚ Å¼ instead).

How should I approach this issue to get correct result?

Specifying UTF-8 in the constructor doesn't make the underlying xml processing library process it as utf8. The following workaround is really hacky, but its works reasonably well.

$encodingHint = '<meta http-equiv="Content-Type" content="text/html; charset=utf-8">';
$dom->loadHTML($encodingHint . $html);

If you're viewing the output in a web browser, send a real http header, not an http-equiv meta tag. This is only for viewing. processing with domdocument specifically needs the meta tag.

header('content-type: text/html; charset=utf-8');
