U+1D48 "ᵈ" Modifier Letter Small D Unicode Character

U+1D48 "ᵈ" Modifier Letter Small D is a superscript or raised lowercase letter D used primarily in phonetic transcription, particularly within the International Phonetic Alphabet, to indicate a variety of modifications to a preceding sound, such as lenition, aspiration, or a voiced dental or alveolar plosive articulation. It belongs to the Phonetic Extensions block of Unicode, which was designed to support specialized linguistic notation for documenting spoken languages. This character functions as a diacritic modifier, meaning it is not typically used standalone but is attached or closely associated with another base character to alter its phonetic value, and it appears in scholarly texts, dictionaries, and language documentation to represent subtle distinctions in pronunciation.
