U+238C "⎌" Undo Symbol Unicode Character

U+238C "⎌" Undo Symbol is a graphical symbol used in computing and user interface design to represent the common action of undoing a previous operation, such as reverting text editing or file changes. Its visual design typically resembles a backward-curving arrow or a broken circle with a leftward notch, intended to evoke the concept of reversing or rolling back to an earlier state. Originally introduced as part of the Miscellaneous Technical block in Unicode 3.0, this character provides a standardized encoding for the undo symbol across different platforms and applications, though it has historically been implemented less frequently than the traditional curved arrow icons found in many software interfaces.
