U+16F76 "𖽶" Miao Vowel Sign Rounded Err Unicode Character

U+16F76 "𖽶" Miao Vowel Sign Rounded Err is a combining diacritical mark used within the Pollard script, which was historically developed for writing the Miao (Hmong) languages. This specific vowel sign modifies a consonant to indicate the sound of a rounded, back vowel similar to the 'err' in the word "her," though with a distinct rounded lip articulation. It belongs to the Miao block of Unicode, added in version 6.1, and is essential for accurately representing certain phonetic distinctions in Miao orthography, particularly in the writing systems used by Christian missionaries and subsequent adaptations for modern Miao dialects.
