New submission from STINNER Victor <vstinner at python.org>:

'@test_6488748_tmpæ' is likely TESTFN_NONASCII which is exposed as test.support.os_helper.TESTFN, but test_io has many many tests using TESTFN.

If someone is able to reproduce the issue, please attempt to identify which test method leaks the temporary file using the command:

./python -m test.bisect_cmd test_io --fail-env-changed -v

After 10-20 minutes, the command should give the name of a single method which creates the temporary file.
