U+02C0 "ˀ" Modifier Letter Glottal Stop Unicode Character

U+02C0 "ˀ" Modifier Letter Glottal Stop is a diacritic mark used primarily in phonetic transcription and linguistic notation to represent a glottal stop articulation or to modify the sound of a preceding or following letter. It appears as a small raised question mark without a dot and is often employed in the International Phonetic Alphabet, as well as in the transcription of various languages such as those in the Americas, to indicate a catch in the throat sound. This character serves as a modifier, typically attached to other letters to show that a glottal stop involves a change in the quality of that sound, such as in ejective consonants or creaky voice.
