U+1FB99 "🮙" Upper Right to Lower Left Fill Unicode Character
Unicode Version 17.0
🮙
U+1FB99 "🮙" Upper Right to Lower Left Fill is a graphical symbol belonging to the Symbols for Legacy Computing block, specifically designed to represent a diagonal fill pattern that covers a cell from its upper right corner down to its lower left corner. This character was introduced in Unicode version 13.0 to support text mode graphics and user interface simulations from vintage computer systems, where such fills were used in low resolution displays or terminal applications. It serves as a visual artifact for encoding retro computing aesthetics, allowing modern text to replicate the blocky, pixel based shading common in early software interfaces.
