Hi Deri,

It's already generated with `-P -e`.

Yup.  These 6 diagnostics are expected, and documented in the "PROBLEMS"
file.

nospace mode for font 'EURO'

Yup.  We're covering that one in bug #65111.

I don't get this one, yet, but that is I think because I have not
cherry-picked the relevant support from your branch onto master yet.

I'm using Okular as well.

The attachment would be 1.5MiB large (a savings of nearly 3 megs over
"old generation" gropdf!) and I don't think Savannah will accept that.
However you can find the file at my Dropbox account.

https://www.dropbox.com/sh/17ftu3z31couf07/AAC_9kq0ZA-Ra2ZhmZFWlLuva?dl=0

It's "groff-man-pages.2024-01-03.pdf".

Let me know how I can be of further assistance.

Regards,
Branden
