# This code runs on Python 2.7 on my Ubuntu 18.04, on staging (Nixos),
# on production (Nixos), on one Travis pipeline, but fails on another
# Travis pipeline - then with a UnicodeDecodeError
# Why had this code worked for months?
# What possibly could have changed (possibly in the setting/os) so
# that the tests breaks now?
# Note: There is no `u` prefix used!!
