Question

When I try to write UTF-8 Strings into an XML file using DomDocument it actually writes the hexadecimal notation of the string instead of the string itself.

Answer 1

To the point answer is:

When your function starts, right after you get the content, do this:

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

And then start the new document etc. Check this as example:

if ( empty( $content ) ) {
    return false;
}
$doc = new DOMDocument('1.0', 'utf-8');
libxml_use_internal_errors(true);
$doc->LoadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

Then do whatever you were intending to do with your code.
