U+0674 "ٴ" Arabic Letter High Hamza Unicode Character

U+0674 "ٴ" Arabic Letter High Hamza is a diacritical mark used in the Arabic script, primarily in the writing systems of certain languages like Kazakh and Urdu, to indicate a glottal stop or a specific vowel quality distinct from the standard Arabic hamza. It appears as a small superscript version of the hamza character, positioned above the baseline, and is encoded separately to facilitate proper text rendering and linguistic precision in digital environments. Its inclusion in Unicode supports the accurate representation of orthographic conventions where this elevated form is necessary, often serving to differentiate phonetic nuances in loanwords or native vocabulary.
