Yes, this is something I screwed up in c1b63af445. Gnus has always
stored group names as raw bytes in.newsrc.eld (at least I believe it
has, you probably know better than I do, it does in my experiments with
Emacs 26, anyway), and only encodes during display. But obviously I've
messed something up between file persistence and display, and I'm
working on sorting it out.
