Box Drawings Vertical Double and Right Single

Box Drawings Vertical Double and Right Single at U+255F forms a junction where a double vertical line continues through the cell and a single horizontal line extends to the right. It is part of the Box Drawing block, a set of printable symbols designed for constructing text-mode frames, tables, and interface borders. Its main use is in monospaced terminal art and legacy text user interfaces, especially where a layout mixes double-line outer borders with single-line internal dividers. For example, a menu or table can use this character on the left edge where a single row separator begins inside a stronger double vertical border. It also appears in plain-text diagrams, documentation, roguelike-style screens, bulletin-board system artwork, and console applications that preserve box-drawing aesthetics. Correct alignment depends on a monospaced font and compatible line-height metrics; in proportional fonts, the intended connection to neighboring box-drawing characters may look broken.
