ASCII 201

Character 201 (É)

Latin-1 Supplement

Latin capital letter É. Common in Western European languages (French, German, Spanish, Portuguese).

Common uses & context

Decimal 201 (0xC9) is Character 201, part of the Latin-1 Supplement (128–255). Latin capital letter É. Common in Western European languages (French, German, Spanish, Portuguese). It renders as 'É' and its binary byte is 11001001.

This is where single-byte ASCII ends and encoding matters. In Latin-1 (ISO-8859-1) 'É' is the single byte 0xC9. In UTF-8 — today's default for the web — the same character is the multi-byte sequence 0xC3 0x89. 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+00C9, and in HTML you can write it as É.

Code snippets

JavaScript

String.fromCharCode(201); // "É"
201.toString(16); // "c9"

Python

chr(201)           # control char É
ord(chr(201))      # 201
hex(201)           # '0xc9'

HTML

&#201;   <!-- numeric entity (no named entity for this character) -->

Programming notes

  • Single byte 0xC9 in Latin-1, but the multi-byte sequence 0xC3 0x89 in UTF-8 — never assume one byte per character above code 127.
  • Unicode code point U+00C9; HTML numeric entity &#201;.
  • 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+00C9. In UTF-8 it encodes to the byte sequence 0xC3 0x89. In legacy Latin-1 (ISO-8859-1) it is a single byte 0xC9, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.

Frequently asked questions

What character is ASCII code 201?

ASCII code 201 is the character 'É' (Character 201). In hexadecimal it is 0xC9, in octal 0311, and in binary 11001001.

What is 0xC9 in ASCII?

Hexadecimal 0xC9 equals decimal 201, which is the character 'É' (Character 201). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0xC9 = 201) and look up that code point.

How do I write the character with code 201 in code?

In JavaScript use String.fromCharCode(201); in Python use chr(201); in HTML use the numeric entity &#201;. In a URL it is percent-encoded as %C9, and in UTF-8 it is stored as the byte sequence 0xC3 0x89.

Is 'É' part of standard ASCII?

No. Standard ASCII covers codes 0–127 only. 'É' is code 201, part of the Latin-1 Supplement (128–255, sometimes called "extended ASCII"). It is a single byte 0xC9 in Latin-1 but a multi-byte sequence (0xC3 0x89) in UTF-8.
