U+11F39 "𑼹" Kawi Vowel Sign Uu Unicode Character

U+11F39 "𑼹" Kawi Vowel Sign Uu is a combining diacritical mark used in the Kawi script, a historical Brahmic writing system employed across Maritime Southeast Asia to write Old Javanese, Sanskrit, and other regional languages. This specific vowel sign represents the long vowel sound "uː" (similar to the U in "rude") and is attached to a consonant base character to alter its inherent vowel, forming a closed syllable. It is part of the Kawi block of Unicode, which was added to support the digital preservation and study of medieval inscriptions and manuscripts from the region.
