The fate-run.sh shell script exports LC_ALL=C before invoking the
test executables; this is probably done for consistency.
When executing Windows binaries with Wine, it normally handles
UTF-8 command line parameters just fine - but with LC_ALL set to
C, it treats them as plain ASCII.
As the unicode command line parameters wasn't the main thing
being tested here, just convert them to plain ASCII, for
portability. This fixes the test for all test configurations that
use Wine.
