What ⎹ means
It marks the right edge of a terminal text cell. A character cell is one fixed-width slot in the text grid used by command-line screens.
The terminal-graphics proposal connects this line family to character sets used by IBM and Heath/Zenith terminals; a reference proposal is dated November 1998. The set had Unicode and ISO approval by May 2000. The opposite edge is ⎸, while horizontal line characters form the top and bottom.
