U+1FBBD "🮽" Negative Diagonal Cross Unicode Character

U+1FBBD "🮽" Negative Diagonal Cross is a symbol within the Symbols for Legacy Computing supplement block, representing a visual element used in early computer and terminal graphics to create negative space or fill a cell with a diagonal cross pattern in reverse video or ink. Unlike a standard diagonal cross that appears as lines, this character inverts the typical display, showing the background color as the cross shape and the foreground as the surrounding area. It was part of the bitmap and text mode interfaces of systems like the ZX Spectrum, where such blocks allowed for simple graphic design and pixel art within a character grid.
