From b7d45c140fde9366a34412dbd318dd7c84bbef14 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Tue, 24 Oct 2023 14:58:06 +0200 Subject: man: encode minushyphen the way groff/man requires it Sparked by a recent LWN article[1], sweeps over the iptables manpages for incorrectly encoded dashes was made by Phil Sutter and myself. An ASCII minushyphen in the source manpage translates to a hyphen in output, so one has to use the sequence "\-" to get a minushyphen in the output, as groff_char(7) explains.
