The FreeBSD 2.7 buildbot is failing because of test_ssl:

test test_ssl failed -- Traceback (most recent call last):

test.pythoninfo:

* sys.filesystem_encoding: US-ASCII


The failure is likely related to the commit 6e8f395001b026daea047cf225dcca5a973ae824, bpo-25404:

Maybe the test should be skipped if the filesystem encoding cannot encode the path?

The issue is not specific to FreeBSD, it depends on the locale (on the Python filesystem encoding).

I reproduced the issue on Linux:

vstinner@apu$ LC_ALL=C ./python -m test test_ssl
Run tests sequentially
0:00:00 load avg: 0.27 [1/1] test_ssl
