"LC_ALL=C ./python -We -m test -vuall -m test_strings test_gdb" still fails for me on Fedora 29.

First list contains 2 additional elements.
First extra element 0:

-  "character '\\u2620' in position 1: ordinal not in range(128): "]


Note: "LC_ALL=C ./python -m test -m test_strings test_gdb" (simpler command) also fails.
