U+23A9 "⎩" Left Curly Bracket Lower Hook Unicode Character
Unicode Version 17.0
U+23A9 "⎩" Left Curly Bracket Lower Hook is a typographic symbol used primarily in mathematical notation and computer science to represent the lower portion of a vertically extended left curly brace, often employed in piecewise functions, set definitions, or branching structures where a tall brace is constructed from multiple connected glyphs. Unlike the standard opening curly brace which is a single character, this hook is part of the "Miscellaneous Technical" Unicode block and functions as a building block for displaying large braces in plain text environments, where it pairs with the Upper Hook (U+23A8) and Middle Piece (U+23A7) to form a seamless vertical bracket. Its visual design resembles a small, upturned corner or a final curved segment that completes the brace's lower left curve without extending vertically, making it distinct from broader punctuation marks. This character can be found in legacy computing systems, terminal emulators, and specialized formatting for equations,
