XML can optionally declare its own encoding:

<?phpxml version="1.0" encoding="UTF-8"?>

You can use the $encoding parameter to provide this information (if missing) or override it (if wrong).

Output is always UTF-8 (that's how libxml works).

Windows users remember to enable php_openssl.dll in your php.ini if you want to be able to use this function (and others) with a HTTPS URL.
