UnicodeEncodeError: 'latin-1' codec can't encode character '\u201c' in position 9: ordinal not in range(256)

Any help appreciated. I've tried google-ing the error and I find lots of unrelated, seemingly unhelpful stuff. I presume this is some system misconfiguration issue, but I've no idea what the problem is:

OS version info (/etc/os-release):

NAME="Ubuntu"
VERSION="16.04.5 LTS (Xenial Xerus)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 16.04.5 LTS"

SUPPORT_URL="http://help.ubuntu.com/"
BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"
VERSION_CODENAME=xenial
UBUNTU_CODENAME=xenial

Result of attempting to run as described on Ubuntu help pages:

$ python3 -OEs aptsources-cleanup.zip

If the issue arises again could you please include the output of the locale command? Thanks.

Will do. I ended up editing the aptsources by hand...
Here's the locale output from the machine that exhibited the problem:
