Character encoding breaks on release upgrade (-d) GUI (lunar to mantic)

[Daniel LaSalle]

Suddenly and without any warning my whole interface upgraded to what seems to be the language of the Minotaur.

I upgraded 2 systems using ```update-manager -d``` and both behaved exactly the same. So I am tempted to conclude this isn't a bug but a feature and should be canceled.

Both upgrades came from 23.04, were set to English language and gradually evolved into the fonts we can see. By "evolved" I mean that some characters began morphing, and then some more. And then some more. It didn't all hit "full Minotaur force" all of a sudden.

What did YOU do on your Thursday night? Me, well, I studied the way of the Minotaur!
