Re: [Groff] Bold \(sq not filled

Agreed.  This does seem to be a bug in groff that needs formerly lodging
somewhere?

For what output devices?

Perhaps due to being derived from V7's source.

It seems -Tps draws \(sq whereas -Tutf8 uses U+25A1.  The neighbouring
U+25A0 is filled so \[u25A0] might do you, depending on the output
device.

    $ printf '.pl 1v\n%s\n' 'a\(sqba\[u25A0]b' | groff -Tutf8
    a□ba■b
    $
    $ printf '.pl 1v\n%s\n' 'a\(sqba\[u25A0]b' | groff -Tutf8 |

Cheers, Ralph.
