Chat archives are not displayed correctly

Good afternoon, at me such problem all archives of chats are displayed in the form of question marks, coding MySql utf-8. In what there can be a problem and how it to correct?

What do your archiving settings look like?

Default archiving settings, I did not touch anything

These are my settings.

I also opted into using the built-in database. It was less of a hassle.

I hopes this helps in some way
