Thank you, Tim.
Fedora is 38 :
$ lsb_release -a
LSB Version:
:core-5.0-amd64:core-5.0-noarch:cxx-5.0-amd64:cxx-5.0-noarch:desktop-5.0-amd64:desktop-5.0-noarch:languages-5.0-amd64:languages-5.0-noarch:printing-5.0-amd64:printing-5.0-noarch
Distributor ID: Fedora
Description: Fedora release 38 (Thirty Eight)
Release: 38
Codename: ThirtyEight
$ evince --version
GNOME Document Viewer 44.3
R version does not matter at all.
Same phenomenon in several versions of R I have installed
simultaneously (from source).
As I mentioned, I'm slightly misusing the list for non-R problem
that I encounter a lot with R {because I like to use
"plotmath"}, so I apologize in advance.
Maybe it's rather a matter of fonts installed in
/usr/share/fonts/ ??
