U+1FBB1 "🮱" Inverse Check Mark Unicode Character

Unicode Version 17.0

🮱

U+1FBB1 "🮱" Inverse Check Mark is a typographic symbol included in the Symbols for Legacy Computing supplement block, which was added to Unicode to represent characters used in early computer systems and terminal interfaces. Depicting a square outline with a diagonal cross or a reversed check mark motif, this specific glyph is part of a set designed to provide visual feedback or status indicators in text-based user interfaces. Its inverted orientation distinguishes it from the standard check mark, often conveying a negative, incorrect, or invalid state in contrast to a positive affirmation. The character is a niche but intentional addition to Unicode, preserving and standardizing graphical symbols from historical computing environments for modern digital use.
