Unicode error with description characters within config.

NetBox version

Python version

3.9

Steps to Reproduce

Config backup seems to run and file is in git. "Last Backup" field in grid goes blank.

Clicking that job shows uid and going to the git dir, cat uid.running does show the valid config.

Clicking the job config specifically though gives a unicode error.

The string that could not be encoded/decoded was: - Fl���� N

Legit that the characters are there. They were imported from Peeringdb via peeringmanager as descriptions for bgp.

            description "Peering: AS32098 - Fl� Networks";
            description "Peering: AS32098 - Fl� Networks";

Expected Behavior

Mask or handle characters without error.

This is an issue as we simply choose to decode as ASCII. I could likely encode/decode as utf but there might be issues with that.
