U+23B4 "⎴" Top Square Bracket Unicode Character

Unicode Version 17.0

U+23B4 "⎴" Top Square Bracket is a typographical symbol used to represent the upper horizontal segment of a square bracket, typically employed in mathematical notation, text editing, or technical diagrams to indicate the top boundary of a grouping or container that spans multiple lines or characters. It belongs to the Miscellaneous Technical block and is often paired with its counterpart, the Bottom Square Bracket (U+23B5), to visually enclose content in a way that mimics the shape of a full bracket split horizontally. Its design resembles a small, flat line with slight vertical end caps, and it serves specific roles in contexts like computer science for denoting Unicode text range markers or in layout descriptions where a full bracket might be unwieldy.
