You don't know how to make a good report? See https://orgmode.org/manual/Feedback.html#Feedback Your bug report will be posted to the Org mailing list. ------------------------------------------------------------------------ (This was first reported to Emacs at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=69483) "mu4e"[1] (a popular Emacs mail client) uses Org to generate its manpages. However, the generated output contains macros that are not understood by groff. After some debugging, Jeremy traced this back to the macro "\fC" used in ox-man.el[2]. Git history shows that this may have been there since the beginning. We tried to find a documentation for the "\fC" macro but has not been able to find one. Jeremy suggests that "C" may be an old alias for Courier, and if that's the case it should be changed to "\f[CR]". Would be great if Org people can confirm.
