U+00C3 "Ã" Latin Capital Letter A with Tilde Unicode Character
Unicode Version 17.0
Ã
U+00C3 "Ã" Latin Capital Letter A with Tilde is a precomposed glyph representing the letter A combined with a diacritical tilde above it, which indicates a nasalized vowel sound in languages such as Portuguese, where it appears in words like "mão" (hand) and "coração" (heart). This character is distinct from the separate sequence of a capital A followed by a combining tilde, as U+00C3 is a single code point in the Latin-1 Supplement block of Unicode, assigned for compatibility with legacy character encodings. Its usage supports the accurate typographic representation of specific phonetic values in written communication, particularly in Romance languages.
