U00E2

U+00E2 is the Unicode code point for the Latin small letter a with circumflex, written as â. Its uppercase counterpart is U+00C2 LATIN CAPITAL LETTER A WITH CIRCUMFLEX. U+00E2 is part of the Latin-1 Supplement block and is commonly used in several Latin-script languages.

In terms of usage, â appears in languages such as French, Portuguese, Romanian, and Vietnamese, where it represents distinct vowel qualities or phonemes. In Romanian, â is treated as a separate vowel letter used in native words, while in French and Portuguese the circumflex often signals a historical change in spelling or vowel length. In Vietnamese, diacritics on vowels indicate tone and vowel quality, with â representing a specific vowel sound in the system of tonal marks.

Encoding details include its decimal value (226) and its UTF-8 representation (two bytes: C3 A2). In HTML, the character can be produced with the named entity â or the numeric entity â. In LaTeX, it can be produced with an accent command such as \^a in many font encodings.

Distinctions and considerations include recognizing U+00E2 as the lowercase form; its uppercase is U+00C2. Because different languages treat â as part of the core alphabet or as a diacritic on a, proper handling may vary in collation, input methods, and typography across systems.
