Groff and RockyLinux 8.5

I want to build some documents with groff. So I installed

dnf -- enablerepo=powertools install groff

Than I want to build the document with

groff -ms -T pdf > decument.pdf

This is the error message:

groff: can't find `DESC' file
groff:fatal error: invalid device `pdf'

This problem should be solved with the groff-perl package. Where I can find this package?

What is the pdfroff in the ‘groff’ package?

How can I use utf-8 characters with pdfroff? I get this error message:

can’t translate character code 246 to special character `:o’ in transparent throughput

I start the build process with this line: pdfroff -Kutf8 -mom > paperboy.pdf
