U+0678 "ٸ" Arabic Letter High Hamza Yeh Unicode Character
U+0678 "ٸ" Arabic Letter High Hamza Yeh is a relatively rare and specialized glyph used in the Arabic script, primarily intended for historical or Quranic orthography where a hamza (the glottal stop) is placed above a final or isolated Yeh (the letter for the "y" sound) in a raised position. Its purpose is to represent a specific phonetic nuance or textual tradition that distinguishes it from more common hamza-carrying forms, such as the standard Yeh with hamza above (ئ). As of current Unicode standards and modern Arabic usage, this character is not commonly employed in contemporary writing or digital communication, and its inclusion helps ensure accuracy in the representation of classical manuscripts and religious texts where such diacritical distinctions are preserved.
