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.

  • Issue: Enable UTF-8 mode by default (implement PEP 686) #133711

Sorry, something went wrong.
