U00C9

U+00C9 is the Unicode code point for the Latin capital letter E with the acute accent (É). It is part of the Latin-1 Supplement block and represents a precomposed character used in several Western European languages to indicate a stressed or modified vowel quality. The corresponding lowercase form is U+00E9 (é).

Encoding and representation: In Unicode, É exists as a single precomposed character. In UTF-8 it is encoded as the byte sequence C3 89, and in UTF-16 it is 00 C9. In HTML and XML, it can be written as É or as numeric references É (decimal) or É (hex). Unicode also supports a decomposed form consisting of the letter E (U+0045) followed by the combining acute accent (U+0301), although the preferred representation for compatibility is the precomposed character.

Usage: É appears in many languages that use the Latin script, including French, Portuguese, Spanish, Irish, Icelandic, and various names and loanwords. It signals a particular vowel quality or stress pattern in orthography and can affect pronunciation, meaning, or emphasis in different linguistic contexts. In alphabetical ordering, treatment of É varies by locale; some systems treat it as a separate letter, while others align it with E for collation.

Related characters: The lowercase equivalent is LATIN SMALL LETTER E WITH ACUTE (U+00E9). Related diacritic forms include other accented E variants such as É, È, Ê, and É in different languages.
