U+1FBE9 "🯩" Right Justified Left Half Black Circle Unicode Character

U+1FBE9 "🯩" Right Justified Left Half Black Circle is a specialized symbol belonging to the Symbols for Legacy Computing block, representing a half-filled circle aligned to the right side of its character cell. It was introduced in Unicode version 13.0 to support the accurate reproduction of early computer and teletext graphics, particularly in contexts where precise visual alignment of monospaced shapes was required. This character visually depicts a circle with its left half filled in black and its right half left empty or white, but technically it is defined as right justified to indicate that the black portion occupies the left side of the bounding box, serving as a historical graphic element for drawing lines, patterns, or partial fills in vintage display systems.
