U+255F "╟" Box Drawings Vertical Double and Right Single Unicode Character

U+255F "╟" Box Drawings Vertical Double and Right Single is a graphic symbol used in text-based user interfaces and plain text tables to form a specific type of junction or connector in box-drawing diagrams. As its name suggests, it combines a double vertical line with a single horizontal line extending to the right, creating a T-shaped intersection where the vertical stem is thicker or doubled compared to the single rightward branch. This character is part of the Unicode Box Drawing block, which standardizes visual characters for creating simple line-art frames, charts, and grids without relying on graphical images. It serves a precise role in layouts that require distinguishing between stronger borders and lighter internal dividers, such as in early computer terminal displays, terminal emulators, command-line tools, or ASCII-like diagrams that mix line weights.
