I'll try that, tho I haven't looked at that code in quite a while, so
it'll take some time for me to figure out how&where to look.

To me this font comes literally out of nowhere.

AFAICT the only relevant face specifications at play here are the two
pieces of font-info in the recipe (and `face-font-family-alternatives`
but this doesn't seem to play any role).

So, how do we end up with the `Century Schoolbook L` family (rather
than either `fixed` or `DejaVu Sans` both of such seem just as
qualified)?

And if `urw` matches `*`, then why doesn't `PfEd` match it as well?
