U+03F2 "ϲ" Greek Lunate Sigma Symbol Unicode Character

U+03F2 "ϲ" Greek Lunate Sigma Symbol is a variant form of the Greek letter sigma, distinguished by its rounded, C-like shape that contrasts with the more common modern sigma (σ or ς). Historically used in ancient and medieval Greek manuscripts, especially in uncial script, this lunate sigma served as a simpler alternative that avoided the word-final ς form. Today, it is occasionally employed in scholarly contexts or mathematical notation and is encoded separately in Unicode to preserve its distinct visual and historical identity within Greek typography.
