[issue37584] Multiple test failures with OSError: [Errno 84] Invalid or incomplete multibyte or wide character on ZFS with utf8only=on

[Dimiter Naydenov]

New submission from Dimiter Naydenov <dimiter at naydenov.net>:

I'm running Ubuntu 19.04 on a ZFS mirrored pool, where my home partition is configured with 'utf8only=on' attribute. I've cloned cpython and after running the tests, as described in devguide.python.org, I have 11 test failures:

== Tests result: FAILURE ==

389 tests OK.

11 tests failed:
    test_cmd_line_script test_httpservers test_imp test_import
    test_ntpath test_os test_posixpath test_socket test_unicode_file
    test_unicode_file_functions test_zipimport

I've been looking for similar or matching reported issues, but could not find one. I'm on the EuroPython 2019 CPython sprint and we'll be looking into this with the help of some of the core devs.
