I did consider that, but the 1980 IBM Displaywriter uses a filled downwards triangle, not a house character, to indicate the center line [0].

But you're right that the Displaywriter inspited 1984 DisplayWrite DOS program [1] did use the house character for the same purpose. (Although, CP437 also included a filled downwards triangle character at 0x1F.)
