Groff will interpret a bare '- ' as a hyphen, and may render it in output as U+2010 HYPHEN. It will interpret an escaped '\-' as a minus sign, and may render it in output as U+2212 MINUS SIGN. I'm not aware of any way to actually *tell* groff that we want the output to be a U+002D HYPHEN-MINUS. Either way, we rely on undefined behaviour of the output drivers which may vary from system to system. Basically, I think groff is just broken. There is a thread at=20 http://lists.gnu.org/archive/html/groff/2015-01/threads.html which I've just discovered, but I'm not sure I can see a conclusion there that I understand. --=20 dwmw2
