U+23A4 "⎤" Right Square Bracket Upper Corner Unicode Character
Unicode Version 17.0
⎤
U+23A4 "⎤" Right Square Bracket Upper Corner is a graphical symbol used primarily in computing and mathematics to represent the top-right corner of a rectangular box or bracket in character cell graphics, specifically within the box-drawing and block element set. It forms part of a system for creating visual frames, tables, or diagrams using text characters, where it pairs with other corner and line elements to construct the upper boundary of a box. This character is distinct from a standard right bracket as it lacks the vertical stroke extending below, making it solely a corner piece for precise typographical alignment in plain text environments.
