ascii/utf8 error when importing Launchpad SSH key with non-ascii/unicode characters

My Launchpad SSH key has a unicode quote character (’) rather than the normal apostrophe (') character in it's comment/key name. This causes an ascii decode error to appear in the installer and it fails to import.

This happened during installation of Ubuntu 20.04.3 ARM (ISO). In my case this was from using an SSH key from the "Secretive" app that keeps SSH keys in the Secure Enclave on M1 Mac's and the character came from the machine's hostname "Trent’s Mac Mini". But I assume any utf8 characters in the comment field will trigger it.

Should be reproducible by adding such a character to your key and importing it, you can try import lp:lathiat for now but that key may be removed down the line.
