`puppet resource user` does not work on Windows French edition

Some basic functionality appears to be broken on a default French Windows that uses code page 850 by default. This uncovered two errors within Puppets logging and output emission at the console - Puppet is trying to use / combine incompatible strings in CP850 and UTF-8.

Note that the problem only impacts puppet resource user and not puppet resource group - so some investigation should be done to fully understand the problem since those should behave similarly. Note also that no other puppet resource commands have been tested.

This was discovered while attempting to replicate PUP-5938 - the first attempt to use puppet resource user also failed on Puppet 4.3.0, but with a different error. Not sure if it's worth investing any time in understanding that issue as well.
