UTF-8 Encoding not applied if content contains inline svg graphics

[heldchen]

when scraping a website that contains inlined svg graphics, the loadContent() function fails to apply the correct encoding as the <?xml version="1.0" encoding="UTF-8"?> of the inlined graphic is preventing adding of encoding header in

DomQuery/src/Rct567/DomQuery/DomQueryNodes.php

Line 358 in 663dba0

if (!$this->xml_mode && $encoding && stripos($content, '<?xml') === false) {

a quick fix would be to just rely on the already set $this->xml_print_pi property:

        if (!$this->xml_print_pi && $encoding) {
            $content = '<?xml encoding="'.$encoding.'">'.$content; // add pi node to make libxml use the correct encoding
            $xml_pi_node_added = true;
        }
