What means
It shows a rightward energy effect.
By 1983, Sharp's MZ-700 offered built-in game graphics; this wave belongs to the European model's alternate display set. A screen-cell setting selected its stored picture, rather than a keyboard key.
Unicode 16.0 (2024) carried it forward as plain text, away from the original screen.
