U+2551 "║" Box Drawings Double Vertical Unicode Character

U+2551 "║" Box Drawings Double Vertical is part of the Box Drawing block, which was designed for creating simple text-based diagrams and forms in monospaced environments. This specific character represents a vertical line composed of two parallel thin strokes, often used to denote a double border or a stronger visual separator between columns or sections in terminal interfaces and code output. It is typically paired with other double-line box drawing characters, such as U+2550 for the horizontal double line, to form complete framed structures without relying on graphical images.
