U+03FE "Ͼ" Greek Capital Dotted Lunate Sigma Symbol Unicode Character

U+03FE "Ͼ" Greek Capital Dotted Lunate Sigma Symbol is a typographic variant of the Greek letter sigma used primarily in ancient and medieval manuscript traditions. Unlike the standard uppercase sigma (Σ), this character features a lunar or crescent-like shape with a dot at its center, distinguishing it from related forms like the plain lunate sigma. It was employed in certain epigraphic and paleographic contexts to represent a sigma sound, often appearing in inscriptions or texts requiring specialized letter forms, and remains of interest today for historical linguistics and digital representation of archaic Greek writing.
