UnicodeEncodeError

[Fjodor42]

I seem to be getting a lot of the following in the log on my instance - what can I do about it?

Hello @Fjodor42, thank you for opening this issue.
Are you able to reproduce the error or you're getting it randomly?

Hello, and thank you for looking into this!

To the best of my knowledge, it happens at some points in time when certain emails, that I'm not sure of which are, are coming in.

It would also seem likely that this is related to another error that I get quite frequently, of which the following is an example:

Probably related, from just now:

Any ideas?
