C3A9

C3A9 is the hexadecimal notation for the two-byte UTF-8 encoding of the Latin small letter e with acute, é. In Unicode, é has the code point U+00E9. In UTF-8, this code point is represented by the byte sequence 0xC3 followed by 0xA9, so the hex string C3A9 corresponds to é in UTF-8.

This encoding is widely used in modern text processing and on the web. In URLs and percent-encoding, é is encoded as %C3%A9, reflecting the same two-byte sequence. By contrast, in ISO/IEC 8859-1 (Latin-1) or Windows-1252, é is encoded as the single byte 0xE9; thus C3A9 is not used in those legacy encodings.

In hex dumps or programming contexts dealing with binary data, you may see the pair C3 A9 representing the character é when the data is UTF-8 encoded. The character é is common across many languages such as French, Spanish, and Portuguese, making correct UTF-8 encoding important for interoperability. Overall, C3A9 refers to the UTF-8 two-byte sequence for the character é, rather than to a separate symbol.
