You just specify the encoding in the root element.

<?xml version="1.0" encoding="us-ascii"?>
<?xml version="1.0" encoding="windows-1252"?>
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" encoding="UTF-16"?>

UTF-8 is the default in lieu of a BOM saying otherwise.
