U+26DE "⛞" Falling Diagonal in White Circle in Black Square Unicode Character

U+26DE "⛞" Falling Diagonal in White Circle in Black Square is a symbol included in the Miscellaneous Symbols block, primarily used in cartography and map legends to denote a landmark such as a quarry, mine, or other significant excavation site. Its design features a white circle containing a single diagonal line, all set within a solid black square, creating a high-contrast glyph meant to be easily identifiable on navigational charts. This character was added to the Unicode Standard in 2008 as part of version 5.2, drawing from symbol sets used in Japanese mapping systems, where it serves a specific functional purpose rather than a decorative or linguistic one.
