U+2319 "⌙" Turned Not Sign Unicode Character
Unicode Version 17.0
⌙
U+2319 "⌙" Turned Not Sign is a typographic symbol that resembles the mathematical "not" sign (¬) rotated 180 degrees, and it was originally included in Unicode for legacy computer and telecommunication code sets where it served as a logical negation or indicator of a reversed condition. Its name and shape derive from the practice of turning the standard negation symbol upside down, though in modern usage it is rarely employed in mainstream mathematics or logic, appearing instead in specialized contexts such as older terminal schematics or technical documentation for historical data formats.
