Thanks for the info. I couldn't know; Ken Whistler didn't CC me in his
reply to your question. It's now clear enough: they agree that 2118's name
is not right.

Yup, that fits. Thanks.
Here is the update for the current groff.

\(bv has been mapped to 0x2502, not 0x2759, because it appears to mean
"bar vertical", not "bold vertical".
