U+31B7 "ㆷ" Bopomofo Final Letter H Unicode Character

U+31B7 "ㆷ" Bopomofo Final Letter H is a linguistic symbol used in the Bopomofo phonetic script, primarily for transcribing Southern Min languages such as Hokkien and Taiwanese, where it represents a glottal stop or a final h sound. This character is part of the Bopomofo Extended block, which supplements the basic Bopomofo system to account for sounds not present in Standard Mandarin. In practical use, "ㆷ" appears as a superscript-like mark attached to the end of syllables, enabling precise phonetic representation of checked tones and final consonants. Its inclusion in Unicode ensures that digital text can accurately reflect the unique phonological features of these regional Chinese languages.
