When I pressed "L" for reply-all I got "No Mailing List found", so I
thought I'd resend it to the list.

I learned that poppler-utils is a debian package. pdftopp is part of
poppler in gentoo, yes.

I found the following quote on the popper wiki [1]

"Poppler is using fontconfig to do the font searching on the system for
fonts that are not embedded into the pdf files. "

I'm perhaps wrong about how "Xft", "Xfd", "Fontconfig" and "Freetype"
relate. Is "Fontconfig" a part of "Xfd" and not "Xft" as I assumed? This
is really confusing...

As I ve said I tried all sort of variants in fontconfig, none of which
affected the rendering of the font in the document.

Can you please shed some light on this? I'm not sure we are on the same
page here.

As far as I checked the version of all these packages are correct.

Thank you for your help,
