Box Drawings Light Horizontal

The Box Drawings Light Horizontal at U+2500 draws a thin horizontal line segment for building text-mode rules, borders, and diagrams. It is a printable symbol in the Box Drawing block, made to align with related corner, junction, and vertical-line characters in monospaced text. Its main home is terminal output and command-line interfaces. Text user interface libraries use it for the top and bottom edges of windows, menu boxes, file managers, progress panels, and dashboard-like screens, often joined with corner characters to make a clean rectangular frame. It is also common in plain-text documentation, issue reports, logs, and copied console output where a visible divider is useful without images or rich formatting. Authors may use it to separate sections, underline headings, or sketch simple tables and flow diagrams that need to survive as text. This character is not the same as a hyphen-minus, en dash, or mathematical minus sign: those carry punctuation or arithmetic meanings, while this one is a line-drawing piece intended to connect visually with other box elements. Alignment depends heavily on a monospaced font; in proportional text it may not form continuous rules.
