About the vertical line extension symbol

Part of the Miscellaneous Technical block, this symbol is a vertical line designed to extend other characters in technical or diagrammatic contexts. It is used in conjunction with taller brackets, braces, or other paired delimiters to create a continuous vertical line of a desired length, often in plain-text renderings of mathematical expressions or structural formulas.

As a non-emoji symbol, it serves a functional role rather than a decorative one, appearing in printed materials and plain-text environments where precise vertical alignment is needed. Its appearance is a simple, unadorned vertical stroke, consistent with its purpose as a building block for larger typographic constructions.
