U+18A9 "ᢩ" Mongolian Letter Ali Gali Dagalga Unicode Character

U+18A9 "ᢩ" Mongolian Letter Ali Gali Dagalga is a specialized diacritical mark used in the Mongolian script, specifically within the Ali Gali system, which was developed to accurately transcribe foreign words, particularly Tibetan and Sanskrit terms in Buddhist texts. Unlike standard Mongolian letters that represent sounds, this character functions as a vocalic symbol to modify the pronunciation of a preceding consonant, often indicating a long or emphasized vowel. Its inclusion in Unicode ensures that scholars and linguists can digitally preserve and reproduce historical Mongolian manuscripts, as the Ali Gali extra letters are essential for representing the full phonetic range required for religious and scholarly works from Mongolia's Buddhist tradition.
