- * specially crafted, in order to be used directly by the browser.

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

- * as 'test1/test2/a-file.pdf#thefragment) will be (hopefully) interpreted by the

- * PDF reader (currently only Adobe Reader plug-in seems to be working that way) called

- * from inside the Internet browser as: 'open the file test1/test2/a-file.pdf

- * and go to named destination thefragment using default zoom'.

- * The conversion is needed because in case of a fragment in the form: Slide%201

- * (meaning Slide 1) as it is converted obeying the Inet rules, it will become Slide25201

- * using this conversion, in both the generated named destinations, fragment and GoToR

- * destination.

- *

- * The names for destinations are name objects and so they don't need to be encrypted

- * even though they expose the content of PDF file (e.g. guessing the PDF content from the

- * destination name).

- *

- * Fhurter limitation: it is advisable to use standard ASCII characters for

- * OOo bookmarks.
