U+0294 "ʔ" Latin Letter Glottal Stop Unicode Character
U+0294 "ʔ" Latin Letter Glottal Stop is a typographic representation of the glottal stop phoneme, a consonant sound produced by briefly closing the vocal cords, which occurs in many languages such as Arabic, Hawaiian, and English in certain dialects (for instance, the sound in the middle of "uh-oh"). It was encoded in Unicode as part of the Latin Extended B block to provide a standardized way to write this common speech sound in linguistic transcription and orthography, distinct from the similar-looking punctuation marks like the apostrophe or the letter Ɂ used in some Canadian Aboriginal languages. Its design is based on a rotated or inverted question mark-like shape without a dot, originally derived from the symbol used by the International Phonetic Alphabet to denote the glottal stop.
