U+11A56 "𑩖" Soyombo Vowel Sign Oe Unicode Character

U+11A56 "𑩖" Soyombo Vowel Sign Oe is a combining vowel mark used in the Soyombo script, an abugida historically employed for writing Mongolian, Tibetan, and Sanskrit in Buddhist contexts. This specific sign modifies a consonant letter to represent the vowel sound "oe," similar to a long or diphthongized vowel in transliteration. Its appearance resembles a curved or looped diacritic attached above or within the consonant character, reflecting the intricate calligraphic style of the Soyombo script, which is known for its ornate and symbolic designs. The Soyombo block (U+11A50–U+11AAF) was added to Unicode in version 10.0 to preserve this cultural script.
