U+21AF "↯" Downwards Zigzag Arrow Unicode Character
Unicode Version 17.0
↯
U+21AF "↯" Downwards Zigzag Arrow is a typographic symbol representing a downward pointing arrow with a zigzag or lightning bolt like pattern in its shaft, distinct from a straight arrow. It is often employed in mathematical notation, electrical engineering diagrams, or as a visual metaphor for a sudden drop, failure, or discharge, such as indicating a short circuit or a rapid decrease in value. Its inclusion in Unicode supports diverse technical and scientific documentation, providing a clear, non alphabetic means to convey these concepts in digital text across different systems and fonts.
