In Portuguese, it appears in words like "canção" to denote a nasal vowel, while in Estonian it represents a distinct vowel phoneme, and in Vietnamese it marks a particular tone. Historically, this character derives from combining a standard Latin "o" with the tilde, which originated as a scribal abbreviation for a nasal "n" in medieval Latin manuscripts. It is encoded in Unicode as a single code point to ensure consistent representation in digital text, and it is part of the Latin-1 Supplement block, making it widely supported across fonts and systems.
