    # the PDF hexadecimal format.

    # Some features of the PDF format appear to require that literal
    # strings be used. One such feature is the /Dest key of a link
    # annotation; if a hex encoded string is used there, the links
    # do not work (as tested in Mac OS X Preview, and Adobe Acrobat
    # Reader).
