22335	tests.user_commands.UtilsTests failure on non-English Windows systems	Zbigniew Siciarz	Zbigniew Siciarz	"While working my way towards #22234, I've noticed that current master doesn't pass the test suite on Windows if the system language is other than English. This is the output from running that test on Windows 7 (Polish language, Python 2.7.2):

This failure appears to be caused by a localized system error. The test expects that a `CommandError` is raised, saying that a program cannot be found. The actual error message is extracted from the original operating system error. On English Windows, the message says ''The system cannot find the file specified'' and the test passes. In case of Polish language, the error says ''Nie można odnaleźć określonego pliku'' (oops, non-ASCII characters here) and the test fails as seen above. Wrapping the system error with `force_text` should solve this problem.
