U02B6

U+02B6 MODIFIER LETTER SMALL R is a character in the Unicode standard. It resides in the Spacing Modifier Letters block (U+02B0–U+02FF) and is categorized as a LETTER, MODIFIER (general category Lm). The glyph resembles a small Latin letter r and is intended for use as a modifier rather than a base letter in text.

In phonetic transcription, particularly within some IPA usage, U+02B6 functions as a modifier letter to indicate rhoticity or rhotacization. It may appear attached to a vowel or consonant to convey a rhoticized quality, depending on the transcription system. The exact meaning is determined by the conventions of the language or framework employing it. Because it is a specialized symbol, it is not always supplied by all fonts, and rendering may vary.

Encoding and typography: The code point is encoded in Unicode as U+02B6. In UTF-8 it is encoded as CA B6. In HTML it can be written as ʶ or ʶ. In many fonts the glyph is shared with other modifier letters, and some fonts may render a glyph that approximates the IPA usage even if they do not provide a dedicated variant.

History and related symbols: U+02DE MODIFIER LETTER RHOTICITY MARK is a different symbol used to mark rhoticity diacritically rather than as a letter. U+02B6 is distinct from such diacritics and should be used according to its encoding instructions.
