From c5085aa6123a31c0ffd213dbddd45829215b5e96 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Wed, 28 May 2025 17:19:50 +0200 Subject: [PATCH] gh-133711: Fix test_regrtest for PYTHONUTF8=1 (GH-134839) Use "backslashreplace" error handler to decode stdout and stderr. Example: vstinner@WIN C:\victor\python\main\build\test_python_worker_8360\x91> "C:\victor\python\main\PCbuild\amd64\python_d.exe" -m test --fast-ci --slow-ci --testdir C:\Users\vstinner\AppData\Local\Temp\tmp0t59e8da test_regrtest_noop1 test_regrtest_noop2 test_regrtest_noop3 test_regrtest_noop4 Notice the "\x91" byte at the end of the first line: it's the non-ASCII U+00E6 character encoded to the OEM cp437 code page.
