After some recent python-related changes, the zfs test suite now fails with:

Traceback (most recent call last):
  File "/opt/test-runner/bin/run", line 913, in <module>
    main()
  File "/opt/test-runner/bin/run", line 907, in main
    testrun.run(options)
  File "/opt/test-runner/bin/run", line 740, in run
    self.testgroups[testgroup].run(self.logger, options)
  File "/opt/test-runner/bin/run", line 495, in run
    test.run(options)
  File "/opt/test-runner/bin/run", line 264, in run
    self.result.stdout, self.result.stderr = self.collect_output(proc)
  File "/opt/test-runner/bin/run", line 228, in collect_output
    fd.read()
  File "/opt/test-runner/bin/run", line 137, in read
    while self._read() is not None:
  File "/opt/test-runner/bin/run", line 149, in _read
    buf = os.read(fd, 4096).decode()
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 24: ordinal not in range(128)

After putting in a workaround for that failure, the next failure happens here:

Traceback (most recent call last):
  File "/opt/test-runner/bin/run", line 913, in <module>
    main()
  File "/opt/test-runner/bin/run", line 907, in main
    testrun.run(options)
  File "/opt/test-runner/bin/run", line 740, in run
    self.testgroups[testgroup].run(self.logger, options)
  File "/opt/test-runner/bin/run", line 499, in run
    test.log(logger, options)
  File "/opt/test-runner/bin/run", line 321, in log
    out.write('%s\n' % line)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 24-25: ordinal not in range(128)

I am not sure if this effects other tests suites aside from zfs-test.
