U+1F791 "🞑" Heavy White Square Unicode Character
Unicode Version 17.0
🞑
U+1F791 "🞑" Heavy White Square is a symbol from the Geometric Shapes Extended block, specifically a bold, thickly outlined square with a hollow white interior. It was introduced in Unicode 7.0 and is intended for use in technical documentation, mapping, or design systems where a clear, heavy border is needed to denote an empty or open space. Unlike filled or plain outline squares, its heavy stroke weight ensures visibility even at small sizes, making it distinct from thin-line alternatives.
