A default installation of the groff PostScript and PDF output devices
does not include a font that supports the Polish language.  Did you
install such a font?  If not, the gropdf(1) manual page explains
how to do that, below "FONT INSTALLATION".

Once you have a font installed, both of the following commands are
supposed to work:

 $ groff -k -mandoc -T pdf /usr/local/man/pl/man6/wesnothd.6 > /tmp/tmp.pdf
 $ pdfroff -k -mandoc /usr/local/man/pl/man6/wesnothd.6 > /tmp/tmp.pdf

(Sorry for the silly example, that's the only Polish manual page
i happen to have installed right now...)

In addition to the options shown above, you might also need the -f
option documented in the groff(1) manual page to actually select the
font family you just installed instead of the default, Times New Roman.

If you have no suitable font family installed, you will see error
messages similar to the following, and wrong glyphs in the output
file:

troff: wesnothd.6:29: warning: can't find special character 'u0073_0301'

troff: wesnothd.6:297: warning: can't find special character 'u0041_0328'

While mandoc tries to make *reading* manual pages simple and hence
does not require any fancy options or configuration for the -T utf8
and -T html output modes, real typesetting to PostScript or PDF is
unfortunately still somewhat tricky even in the 21st century and
still requires configuring quite a bit of stuff...  :-(

Yours,
  Ingo
