Creating Unicode bookmarks

A bookmark in a PDF document labels a place within the PDF document to serve as a destination, usually a heading or a graphic. After you add a bookmark, you can create a hyperlink elsewhere in the same PDF document and connect it to that bookmark. When the reader clicks on that link the viewer will take the reader to the page or a section of a page in the PDF where that bookmark is found. The bookmark is entered in the outline dictionary and appears on the left side of the Adobe Acrobat or Reader page.

A bookmark title needs to be in PDFDocEncoding or UTF-16BE (including the byte order marker) for Japanese or other non-Latin languages.
