bug#35816: 26.2; set-frame-font cannot set some fonts which autocomplete suggests due to dashes in names. I.e. gnu-unifont

It's wrong in that if you type RET, Emacs rejects it.

any fonts that have a "gnu" in the foundry name (or perhaps I've just
installed the wrong package?).

But in what way is that font description wrong?
