U+01CF "Ǐ" Latin Capital Letter I with Caron Unicode Character
Unicode Version 17.0
Ǐ
U+01CF "Ǐ" Latin Capital Letter I with Caron is a grapheme used in certain orthographies, most notably in the Pinyin romanization of Mandarin Chinese to represent the third tone on the letter I, and in some African languages for phonetic transcription. It appears as a standard uppercase I with a wedge or caron diacritic above it, resembling a small v shape, which modifies the vowel sound or indicates tone without altering its basic shape. This character is distinct from the similar looking dotless i with caron and is primarily employed in specialized linguistic or academic contexts rather than in everyday text.
