U+1E90 "Ẑ" Latin Capital Letter Z with Circumflex Unicode Character
U+1E90 "Ẑ" Latin Capital Letter Z with Circumflex is a modified version of the standard Latin letter Z, distinguished by the addition of a circumflex diacritic above it. This character is primarily used in certain romanization systems for languages such as Mandarin Chinese, where it can represent a voiced retroflex affricate sound, and it appears in a few lesser-known orthographies or transcription schemes for African languages. The circumflex marker itself often indicates a specific phonetic nuance or tone, notably a falling then rising contour in tonal contexts, though the letter remains relatively rare in everyday modern typography. It belongs to the Latin Extended Additional block of Unicode, ensuring its availability for precise linguistic notation and digital text representation.
