New submission from Jack Howarth:
The Python 3.x test suite produces a new regression on macOS 10.13 under the
new APFS filesystem when executing the test_undecodable_filename() test from
Lib/test/test_httpservers.py. The error appears as...
======================================================================
ERROR: test_undecodable_filename

APFS accepts only valid UTF-8 encoded filenames for creation, and preserves
both case and normalization of the filename on disk in all variants..
Some differences between how APFS and HFS+ handle filenames include the
following:
...
• APFS doesn’t allow files to be created with filenames that contain
unassigned codepoints in the Unicode 9.0 standard, whereas HFS+ does.
