U+2556 "╖" Box Drawings down Double and Left Single Unicode Character

U+2556 "╖" Box Drawings down Double and Left Single is a visual element from the Box Drawing block, designed for creating simple line-based diagrams and text interfaces. It consists of a double vertical line extending downwards from the junction point, combined with a single horizontal line extending to the left. This specific combination allows it to form a corner or intersection in a grid pattern, where the right side and upper side remain open. It is commonly used in legacy terminal graphics, plain text tables, and technical documentation to construct borders or structural outlines with mixed line weights, offering a precise typographic tool for drawing boxy layouts without relying on images.
