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 Yucca, https://jkorpela.fi pe 13.6.2025 klo 20.14 陶铂玉 via Unicode ([email protected]) kirjoitti: > Unicode mail list: > I am seeking the REDO SYMBOL (assumed corresponding with UNDO SYMBOL) in > the Miscellaneous Technical block but have not found it.
