It's changed a bit over the years, but 2000's http://git.savannah.gnu.org/cgit/groff.git/tree/src/roff/nroff/nroff.sh?id=e092fba45175220aeee4912da9e2b96228a798b3 used to set -T's value from locale(1)'s output, or LC_ALL/LC_CTYPE/LANG, and then let the -T argument override it only if it was ascii, latin1, or utf8, or else silently ignore the option. So it's not surprising you can't recall. :-) git goes back no further. > It does. However, in your nroff line above, you are searching for > \[-+], not \[+-], which is not the same. Yes, sorry, I didn't notice the distinction! Now I know there's a minusplus as well as a plusminus. Cheers, Ralph.
