[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.
