U+2AEA "⫪" Double down Tack Unicode Character
Unicode Version 17.0
⫪
U+2AEA "⫪" Double down Tack is a typographical symbol included in the Supplemental Mathematical Operators block, designed for use in formal logic and mathematical notation. It visually resembles two downward-pointing tacks, or T-shaped symbols, stacked vertically, and it is typically employed to represent a specific relational or logical operation, such as a double reversal or a particular type of implication or ordering in advanced proof theory. As a specialized character, it supports precise expression in technical texts where standard operators are insufficient, and it is encoded for compatibility with mathematical typesetting systems like LaTeX and Unicode-aware software.
