Assistance with REDO SYMBOL

[Jukka K. Korpela]

I had never noticed U+238C UNDO SYMBOL ⎌ before, still less seen it in
text, To me, the common icon for undo in user interfaces is more like an
anticlockwise arrow (like U+21BA ANTICLOCKWISE OPEN CIRCLE ARROW ↺), with a
clockwise arrow as its counterpart for redo. I would first ask why UNDO
SYMBOL was included, and then whether similar arguments apply to a redo
symbol. Specifically, where do they appear in texts? Perhaps in manuals
where they refer to user interface icons, but this is hardly sufficient for
characterhood.

If UNDO SYMBOL was included due to its appearance in some user interfaces
(and manuals related to them) decades ago. Grok says it cannot find any
examples of its use in texts. It would probably be difficult to find any
use of a similar symbol for redo. Mere symmetry (“when you have undo, you
should also have redo”) would hardly suffice
