U+23FB "⏻" Power Symbol Unicode Character
Unicode Version 17.0
⏻
U+23FB "⏻" Power Symbol is a standardized graphical icon used to represent the power on/off state for electronic devices, typically associated with the universally recognized circle and line design that indicates a power button. Originally encoded in Unicode 9.0 in 2016 as part of the Miscellaneous Technical block, this symbol serves as a typographic alternative to using images or proprietary fonts in digital interfaces, documentation, and user manuals. Its design, featuring a vertical line inside a partially open circle, derives from the binary convention where a 1 (line) and 0 (circle) combine to signify toggling between an energized and de-energized state.
