ASCII 180
Acute Accent (´)
Latin-1 Supplement
Latin-1 character.
Common uses & context
Decimal 180 (0xB4) is Acute Accent, part of the Latin-1 Supplement (128–255). Latin-1 character. It renders as '´' and its binary byte is 10110100.
This is where single-byte ASCII ends and encoding matters. In Latin-1 (ISO-8859-1) '´' is the single byte 0xB4. In UTF-8 — today's default for the web — the same character is the multi-byte sequence 0xC2 0xB4. 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+00B4, and in HTML you can write it as ´ or ´.

Code snippets
JavaScript
String.fromCharCode(180); // "´"
180.toString(16); // "b4"Python
chr(180) # control char ´
ord(chr(180)) # 180
hex(180) # '0xb4'HTML
´ <!-- named entity -->
´ <!-- numeric entity -->Programming notes
- ▸Single byte 0xB4 in Latin-1, but the multi-byte sequence 0xC2 0xB4 in UTF-8 — never assume one byte per character above code 127.
- ▸Unicode code point U+00B4; HTML entity ´.
- ▸If '´' 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+00B4. In UTF-8 it encodes to the byte sequence 0xC2 0xB4. In legacy Latin-1 (ISO-8859-1) it is a single byte 0xB4, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.
Frequently asked questions
What character is ASCII code 180?
ASCII code 180 is the character '´' (Acute Accent). In hexadecimal it is 0xB4, in octal 0264, and in binary 10110100.
What is 0xB4 in ASCII?
Hexadecimal 0xB4 equals decimal 180, which is the character '´' (Acute Accent). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0xB4 = 180) and look up that code point.
How do I write the character with code 180 in code?
In JavaScript use String.fromCharCode(180); in Python use chr(180); in HTML use the numeric entity ´ or the named entity ´. In a URL it is percent-encoded as %B4, and in UTF-8 it is stored as the byte sequence 0xC2 0xB4.
Is '´' part of standard ASCII?
No. Standard ASCII covers codes 0–127 only. '´' is code 180, part of the Latin-1 Supplement (128–255, sometimes called "extended ASCII"). It is a single byte 0xB4 in Latin-1 but a multi-byte sequence (0xC2 0xB4) in UTF-8.
