What ⌁ means
They are two visible signs for the same control instruction. ⌁ is the graphic sign associated with ISO 2047; ␄ is Unicode's control picture for the same instruction. A control picture makes a code that normally does not print readable. Both signs represent the instruction; neither is the underlying control code.
