U+20EB "⃫" Combining Long Double Solidus Overlay Unicode Character
Unicode Version 17.0
⃫
U+20EB "⃫" Combining Long Double Solidus Overlay is a diacritical mark designed to be placed over or through a preceding base character to create a modified symbol, most commonly for canceling, negating, or indicating the absence of a mathematical relation, such as in the formation of a "not equal to" sign when combined with an equals sign. It is a combining character, meaning it must always follow another character in text to form a composite glyph, and it features two parallel slanted lines that span the height of the base character. This overlay is used in specialized notation within mathematics and formal logic, and its visual effect is distinct from the similar but single-stroke "Combining Long Solidus Overlay" (U+0338).
