Tilde Operator With Dot Above Symbol Meaning
⩪ (Unicode U+2A6A) is “TILDE OPERATOR WITH DOT ABOVE.” Conceptually, it’s a tilde-like operator distinguished by a dot placed above the tilde stroke. In practice, symbols like this are used to represent a particular kind of relation, transformation, or annotated operator in mathematical typography—especially when plain tilde (~) is not specific enough. Its exact semantics depend on the system, document, or font conventions you’re working with. When writing, typesetting, or styling technical text, treat ⩪ as a distinct operator glyph rather than a normal tilde.
Common uses

- •Marking a specialized relation or approximation-like notation in technical documents
- •Replacing plain tilde (~) to improve clarity in equations and proofs
- •Labeling or annotating variables/operators in educational math materials
- •UI/typography for formula editors or symbol pickers
