U+1FBE8 "🯨" Top Justified Lower Half Black Circle Unicode Character

U+1FBE8 "🯨" Top Justified Lower Half Black Circle is a symbol from the Symbols for Legacy Computing supplement, designed to represent a half-filled black circle where the filled portion occupies the lower half and is aligned to the top of the character's bounding box. This glyph is part of a larger set of retro computing and teletext graphic characters, used to recreate the blocky, pixel-style graphics of early computer displays and terminals. Its specific shape, a dark lower semicircle with a clear upper half, can serve in data visualization, diagram notation, or as a placeholder for partially filled states in legacy system emulation.
