U+1D34 "ᴴ" Modifier Letter Capital H Unicode Character

U+1D34 "ᴴ" Modifier Letter Capital H is a superscript or raised version of a capital H, used primarily in phonetic transcription as a diacritic to indicate aspiration, a strong h sound, or as a tone or length marker in the International Phonetic Alphabet and certain linguistic notations. It belongs to the Phonetic Extensions block of Unicode, where it functions as a modifying symbol that attaches to the preceding character, often to denote a voiceless or breathy release in speech sounds. This character is distinct from a regular superscript H and is encoded for precise representation in digital text, ensuring accurate rendering in linguistic and academic publications.
