U+27EC "⟬" Mathematical Left White Tortoise Shell Bracket Unicode Character

Unicode Version 17.0

U+27EC "⟬" Mathematical Left White Tortoise Shell Bracket is a specialized punctuation symbol used primarily in mathematical notation, particularly in East Asian contexts, to denote grouping or ordering within expressions, often functioning as a paired bracket with its right counterpart U+27ED "⟭". Its name derives from the visual resemblance of the bracket's shape to the outline of a tortoise shell, with the "white" modifier indicating an open or hollow design rather than a solid form. This character belongs to the Miscellaneous Mathematical Symbols-A block and is typically employed in advanced mathematical typesetting, such as in texts on set theory or algebra, where it serves as a decorative or culturally specific alternative to more common brackets like parentheses or square brackets.
