U+10A78 "𐩸" Old South Arabian Letter Zayn Unicode Character

U+10A78 "𐩸" Old South Arabian Letter Zayn is a symbol from the ancient script used between roughly the 9th century BCE and the 6th century CE to write the Old South Arabian languages, including Sabaic, Qatabanic, and Hadramitic. This letter represents the consonant sound /z/ and holds a position in the Old South Arabian alphabet, which was primarily used for monumental inscriptions carved in stone or metal across the Arabian Peninsula, particularly in modern-day Yemen. The script, written from right to left, was derived from the South Semitic script family and later influenced the development of the Ethiopic script used for Ge'ez.
