+"""The runner's status glyphs must not crash narrow console encodings.
+
+On native Windows, piped or legacy-console stdio defaults to cp1252, which
+cannot encode the runner's ✓/✗ progress glyphs — before the fix, the first
+per-file status line killed the whole run with UnicodeEncodeError. The
+failure depends only on the stream's encoding, so these tests pin it on
+every OS by building a cp1252 stream explicitly.
