U+0373 "ͳ" Greek Small Letter Archaic Sampi Unicode Character

U+0373 "ͳ" Greek Small Letter Archaic Sampi is a historical letter used in ancient Greek inscriptions and some early manuscripts as a variant of the Greek alphabet, primarily representing a sibilant sound similar to "ss" or "ts" and serving as a precursor to the later standard letter "sampi" (ϡ). This archaic form is distinct from the more common majuscule and minuscule sampi characters found in later Greek writing, and it is included in Unicode to support scholarly transcription and digital representation of ancient texts. Its usage declined after the classical period, but it remains of interest to epigraphists and paleographers studying the evolution of the Greek script.
