  [Impact]

  It is impossible to set up or manipulate a printer with a PPD file
  which is not UTF-8-encoded and no plain ASCII. Even worse, if such a
  PPD is installed into the system's PPD repository, the corresponding
  printer(s) will not auto-setup.

  [Test Case]

  Take a PPD file which is not UTF-8-encoded, for example a PPD file for
  Windows with Windows-1252 encoding. Try to set up a que with it or to
  change an existing queue to use it by means of system-config-printer.
  system-config-printer will crash.

  With the proposed package the PPD can be used without problems.

  [Regression Potential]

  The changes are very simple and therefore the regression potential is
  low.
