594 : * In this way the fragment part of a hyperlink to a PDF file (e.g. something

599 : * The conversion is needed because in case of a fragment in the form: Slide%201
600 : * (meaning Slide 1) as it is converted obeying the Inet rules, it will become Slide25201
601 : * using this conversion, in both the generated named destinations, fragment and GoToR
