U+23B7 "⎷" Radical Symbol Bottom Unicode Character
Unicode Version 17.0
U+23B7 "⎷" Radical Symbol Bottom is a specialized glyph used in mathematical and technical notation to represent the lower horizontal stroke and the lower portion of the vertical stroke of a square root or radical sign, effectively completing a root symbol when paired with an upper radical or vinculum. It belongs to the Miscellaneous Technical block of the Unicode standard, where it serves a distinctly compositional purpose rather than functioning as a standalone character in typical text. Its inclusion allows for precise construction of radical expressions in plain text or in environments where proper mathematical rendering is limited, such as in terminal displays or early text-based formatting systems. Though its everyday use is rare outside of niche typesetting or legacy computing contexts, the symbol remains an important tool for accurately representing complex mathematical notation without requiring graphical rendering.
