PHP DOMDocument loadHTML not encoding UTF-8 correctly

Question

I\'m trying to parse some HTML using DOMDocument, but when I do, I suddenly lose my encoding (at least that is how it appears to me).

$profile = \"

        

Answer 1

Use it for correct result

$dom = new DOMDocument();
$dom->loadHTML('' . $profile);
echo $dom->saveHTML();
echo $profile;

This operation

mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8');

It is bad way, because special symbols like < ; , > ; can be in $profile, and they will not convert twice after mb_convert_encoding. It is the hole for XSS and incorrect HTML.
