Unicode Version 17.0
⎞
U+239E "⎞" Right Parenthesis Upper Hook is a typographic symbol used primarily in mathematical and technical notation to represent the upper curved segment of a right parenthesis. It forms part of a set of bracket extension characters, often employed in conjunction with other hook and extension pieces to compose large, vertically adjustable parentheses for displayed equations or tall expressions in plain text environments where standard scalable fonts are not available. This character allows for precise visual alignment when building custom-sized delimiters, ensuring that the upper curve of a right parenthesis correctly connects to vertical extension bars, thereby maintaining the intended structural appearance of complex formulas.
