U+16F6B "𖽫" Miao Vowel Sign Ua Unicode Character

U+16F6B "𖽫" Miao Vowel Sign Ua is a diacritical mark used in the Miao (Pollard Phonetic) script, specifically representing the vowel sound "ua." This script, also known as Pollard Miao, was developed in the early 20th century by missionary Samuel Pollard for writing the A-Hmao language and other Hmongic languages of southwestern China. The vowel sign combines with a consonant symbol to modify its pronunciation, and it appears as a small circle or dot placed above or beside the base character. As part of the Miao block in Unicode (range U+16F00 to U+16F9F), this character helps preserve and digitize the writing system, which is still used in religious and educational contexts for certain Miao communities.
