U+01D2 "ǒ" Latin Small Letter O with Caron Unicode Character
Unicode Version 17.0
ǒ
U+01D2 "ǒ" Latin Small Letter O with Caron is a precomposed character in the Latin Extended-B block, representing the letter "o" with a caron or háček diacritic placed above it. This character is used in several languages for phonetic transcription and in the orthographies of specific languages such as Pinyin for Mandarin Chinese, where it denotes a falling-rising tone on the vowel "o," or in some African languages like Ngbaka and Mbandja to indicate a distinct vowel quality or tone. It can also be expressed as the combination of a plain "o" followed by the combining caron U+030C, but the precomposed form U+01D2 is supported for compatibility and simpler encoding in text that requires this specific accented letter.
