ASCII 233
Character 233 (é)
Latin-1 Supplement
Latin small letter é. Common in Western European languages.
Common uses & context
Decimal 233 (0xE9) is Character 233, part of the Latin-1 Supplement (128–255). Latin small letter é. Common in Western European languages. It renders as 'é' and its binary byte is 11101001.
This is where single-byte ASCII ends and encoding matters. In Latin-1 (ISO-8859-1) 'é' is the single byte 0xE9. In UTF-8 — today's default for the web — the same character is the multi-byte sequence 0xC3 0xA9. Treating a Latin-1 byte as UTF-8 (or vice versa) is the usual reason accented letters and symbols turn into mojibake like é or €. The Unicode code point is U+00E9, and in HTML you can write it as é.

Code snippets
JavaScript
String.fromCharCode(233); // "é"
233.toString(16); // "e9"Python
chr(233) # control char é
ord(chr(233)) # 233
hex(233) # '0xe9'HTML
é <!-- numeric entity (no named entity for this character) -->Programming notes
- ▸Single byte 0xE9 in Latin-1, but the multi-byte sequence 0xC3 0xA9 in UTF-8 — never assume one byte per character above code 127.
- ▸Unicode code point U+00E9; HTML numeric entity é.
- ▸If 'é' shows as mojibake, the encoding declared and the encoding used disagree — align both on UTF-8.
Unicode & UTF-8 note
In Unicode this is U+00E9. In UTF-8 it encodes to the byte sequence 0xC3 0xA9. In legacy Latin-1 (ISO-8859-1) it is a single byte 0xE9, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.
Frequently asked questions
What character is ASCII code 233?
ASCII code 233 is the character 'é' (Character 233). In hexadecimal it is 0xE9, in octal 0351, and in binary 11101001.
What is 0xE9 in ASCII?
Hexadecimal 0xE9 equals decimal 233, which is the character 'é' (Character 233). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0xE9 = 233) and look up that code point.
How do I write the character with code 233 in code?
In JavaScript use String.fromCharCode(233); in Python use chr(233); in HTML use the numeric entity é. In a URL it is percent-encoded as %E9, and in UTF-8 it is stored as the byte sequence 0xC3 0xA9.
Is 'é' part of standard ASCII?
No. Standard ASCII covers codes 0–127 only. 'é' is code 233, part of the Latin-1 Supplement (128–255, sometimes called "extended ASCII"). It is a single byte 0xE9 in Latin-1 but a multi-byte sequence (0xC3 0xA9) in UTF-8.
