What 🮼 means
It was a small graphic for an Apple II text-screen interface.
Apple's 1989 developer note says MouseText made Apple II text screens work like a desktop interface. This mark occupied the caret (^) position ($5E).
Enhanced Apple IIe, IIc and IIGS models displayed MouseText in $40–$5F when video firmware, MouseText mode and inverse (reverse-video) mode were enabled. An unenhanced IIe showed inverse capitals there, so the same value looked different.
