U+02B3 "ʳ" Modifier Letter Small R Unicode Character

U+02B3 "ʳ" Modifier Letter Small R is a superscript or raised version of the lowercase letter R, classifying it as a modifier letter used primarily in phonetic transcription and linguistic notation. It serves as a diacritic-like symbol that indicates a specific phonetic quality, often representing a rhotic or r-colored sound, and is employed in the International Phonetic Alphabet (IPA) as an occasional superscript for modified r articulations. The character is encoded in the Spacing Modifier Letters block of Unicode, where it functions as a standalone glyph rather than a combining mark, allowing it to be placed after a base letter to denote features such as secondary articulation or a reduced, non-syllabic r sound in descriptive linguistics.
