Carsten Kunze reported an issue with \(sq to the list: http://lists.gnu.org/archive/html/groff/2014-05/msg00042.html

Apparently, \(sq is normally an empty square, as shown in CSTR 54, but filled if the font is bold. That's with 7th Edition troff and Heirloom troff. The latter does this for PostScript output using the PostScript in troff/troff.d/font/devpost/charlib/sq which checks for Bold/Heavy/Ultra fonts. I don't think it does it for UTF-8 terminal output.

More research into 7th Ed./Plan 9's behaviour is needed to determine it's a deliberate effect and reproduce it across output devices.
