613 * specially crafted, in order to be used directly by the browser.
614 * In this way the fragment part of a hyperlink to a PDF file (e.g. something
615 * as 'test1/test2/a-file.pdf#thefragment) will be (hopefully) interpreted by the
616 * PDF reader (currently only Adobe Reader plug-in seems to be working that way) called
617 * from inside the Internet browser as: 'open the file test1/test2/a-file.pdf
618 * and go to named destination thefragment using default zoom'.
619 * The conversion is needed because in case of a fragment in the form: Slide%201
620 * (meaning Slide 1) as it is converted obeying the Inet rules, it will become Slide25201
621 * using this conversion, in both the generated named destinations, fragment and GoToR
622 * destination.
623 *
624 * The names for destinations are name objects and so they don't need to be encrypted
625 * even though they expose the content of PDF file (e.g. guessing the PDF content from the
626 * destination name).
627 *
628 * Fhurter limitation: it is advisable to use standard ASCII characters for
629 * OOo bookmarks.
