gbranden pushed a commit to branch master
in repository groff.
commit 132182bd714a7b327bae1627831836cd1484522b
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

[tmac]: Fix Savannah #58930.
* tmac/fallbacks.tmac: Define fallback characters for many code points
from the Unicode General Punctuation Block. This is to ease migration
from other documentation formats; in many cases there are more
idiomatic *roff ways of getting results that typeset better and are
amenable to fine tuning. For instance, Unicode defines spaces and
dashes of various discrete widths; when typesetting with *roff, you
can have a space or dash (among other things) of any length achievable
by the output device.
* tmac/ps.tmac: Migrate non-breaking hyphen fallback character
definition from here to the foregoing.
Fixes <https://savannah.gnu.org/?58930>. Thanks to Dave Kemper for the
report and discussion.
