U+11A59 "𑩙" Soyombo Vowel Sign Vocalic R Unicode Character

U+11A59 "𑩙" Soyombo Vowel Sign Vocalic R is a diacritical mark used in the Soyombo script, an abugida historically employed to write Mongolian and Tibetan languages, most notably in Buddhist texts and the Soyombo symbol itself. This vowel sign indicates a vocalic 'r' sound, functioning as a syllable-forming vowel rather than a consonant, and it is placed above or attached to a base consonant character to modify its pronunciation. Part of the Soyombo block added to Unicode in version 10.0 in 2017, this character helps preserve a unique writing system developed in the 17th century by the Mongolian monk and scholar Zanabazar, reflecting the script's role in religious and cultural documentation.
