What 𜲋 means

It supplied a ready-made pattern for the display.

Ohio Scientific’s 540 video board, which drove the computer’s display, used a character-generator chip that stored dot patterns for screen cells. In its March/April 1978 journal, the company describes built-in graphics characters for plotting and video games.

Why does 𜲋 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
