U+23DA "⏚" Earth Ground Unicode Character

U+23DA "⏚" Earth Ground is a graphical symbol in the Miscellaneous Technical block that represents the concept of electrical ground, specifically the earth ground connection used in circuit diagrams and electronics schematics. Depicted as three horizontal lines of decreasing length stacked vertically, it visually resembles the standard IEC and IEEE symbol for a ground connection, often distinguished from a chassis ground or signal ground to denote a direct physical connection to the earth. This character was added to the Unicode Standard in version 4.1, released in 2005, to provide a standardized digital representation for technical documentation, allowing engineers and hobbyists to include the symbol in text-based notes, diagrams, and code without relying on images or font-specific glyphs.
