U+01DC "ǜ" Latin Small Letter U with Diaeresis and Grave Unicode Character
U+01DC "ǜ" Latin Small Letter U with Diaeresis and Grave is a composite glyph used in certain Latin-based orthographies, such as the Pinyin romanization of Mandarin Chinese, where it represents a tightly rounded, front vowel sound [y] pronounced with a falling then level tone, often transcribed as "ǜ" in syllables like "nǜ" (女). This character is formed by combining a standard "u" with two diacritical marks a diaeresis (two dots above) indicating the vowel shift from [u] to [y], and a grave accent (a left-slanting mark) signifying a specific tonal contour. It is encoded in the Unicode Latin Extended-B block and is distinct from similar characters like "ǚ" (U+01DA) which uses a caron instead of a grave accent. The glyph appears in specialized dictionaries, linguistic texts, and digital typography for precise phonetic or tonal transcription.
