    # This is used to differentiate strings that must be encoded as a *literal*
    # string, versus those that can be encoded in 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).
