U+03F8 "ϸ" Greek Small Letter Sho Unicode Character

U+03F8 "ϸ" Greek Small Letter Sho is a historical letter used in the Greek script, primarily associated with the Bactrian language of ancient Central Asia. It was employed to represent a specific consonant sound, likely the postalveolar fricative /ʃ/ (like the English "sh"), and appears in inscriptions and manuscripts from the Greco-Bactrian and Indo-Greek kingdoms. Though derived from the Greek alphabet, the sho character became obsolete after the fall of these kingdoms and is no longer part of modern Greek, being recognized today mainly for scholarly purposes in epigraphy and historical linguistics.
