Research direction
Reproduce the case with the uutils stat binary using the invalid byte shown in the report, then compare its diagnostic with gnustat. Trace the stat command's filename rendering and identify the existing tests for invalid or non-UTF-8 paths; done means the diagnostic preserves an escaped representation instead of displaying U+FFFD.
