“ϟ” U+03DF: Greek Small Letter Koppa

ℹ️ About

The Greek Small Letter Koppa (ϟ) is a historical character used primarily for ancient Greek numerical notation, representing the value 90. Unlike the earlier “closed” form of Koppa, the U+03DF codepoint represents the “zig-zag” or numerical style commonly found in Greek manuscripts and modern typography to distinguish it from alphabetic letters.
