U+1E01C "𞀜" Combining Glagolitic Letter Tsi Unicode Character

U+1E01C "𞀜" Combining Glagolitic Letter Tsi is a combining diacritical mark used in the Glagolitic script, an early Slavic alphabet developed by Saints Cyril and Methodius in the 9th century. This character is designed to be placed over or around a base Glagolitic letter to modify its sound, representing the phoneme /ts/ similar to the English "ts" in "bits". Part of the Glagolitic Supplement block, it serves as a crucial component for accurately encoding historical liturgical and literary texts, particularly those from Old Church Slavonic, where such diacritics denote specific phonetic nuances or paleographic features in manuscript traditions.
