U+255B "╛" Box Drawings Up Single and Left Double Unicode Character

U+255B "╛" Box Drawings Up Single and Left Double is a graphical element from the Box Drawing block used primarily in text-based user interfaces and terminal applications to create framed boxes and tables. It represents a corner or junction where a single vertical line extends upward from below and a double horizontal line extends to the left from the right side, forming a T-like shape with distinct line weights. This character allows for precise visual structuring of borders when mixing single and double line styles, often employed in legacy command line programs or ASCII art to indicate hierarchy or separation within a grid.
