U+16F7A "𖽺" Miao Vowel Sign Ei is a diacritical mark used in the Pollard Miao script, an orthography developed in the early 20th century by missionary Samuel Pollard to write the A-Hmao and related Hmongic languages. This specific sign modifies a consonant character by indicating the vowel sound "ei," and it belongs to the Unicode block titled Miao, which encodes these tonal and vowel signs as combining marks or spacing forms. Its inclusion in the Unicode Standard ensures that digital text representing Miao languages can accurately reflect the phonetic distinctions necessary for reading and writing, preserving an important part of linguistic heritage in southern China and Southeast Asia.
