ASCII 175
Macron (¯)
Latin-1 Supplement
Latin-1 character.
Common uses & context
Decimal 175 (0xAF) is Macron, part of the Latin-1 Supplement (128–255). Latin-1 character. It renders as '¯' and its binary byte is 10101111.
This is where single-byte ASCII ends and encoding matters. In Latin-1 (ISO-8859-1) '¯' is the single byte 0xAF. In UTF-8 — today's default for the web — the same character is the multi-byte sequence 0xC2 0xAF. 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+00AF, and in HTML you can write it as ¯ or ¯.

Code snippets
JavaScript
String.fromCharCode(175); // "¯"
175.toString(16); // "af"Python
chr(175) # control char ¯
ord(chr(175)) # 175
hex(175) # '0xaf'HTML
¯ <!-- named entity -->
¯ <!-- numeric entity -->Programming notes
- ▸Single byte 0xAF in Latin-1, but the multi-byte sequence 0xC2 0xAF in UTF-8 — never assume one byte per character above code 127.
- ▸Unicode code point U+00AF; 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+00AF. In UTF-8 it encodes to the byte sequence 0xC2 0xAF. In legacy Latin-1 (ISO-8859-1) it is a single byte 0xAF, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.
Frequently asked questions
What character is ASCII code 175?
ASCII code 175 is the character '¯' (Macron). In hexadecimal it is 0xAF, in octal 0257, and in binary 10101111.
What is 0xAF in ASCII?
Hexadecimal 0xAF equals decimal 175, which is the character '¯' (Macron). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0xAF = 175) and look up that code point.
How do I write the character with code 175 in code?
In JavaScript use String.fromCharCode(175); in Python use chr(175); in HTML use the numeric entity ¯ or the named entity ¯. In a URL it is percent-encoded as %AF, and in UTF-8 it is stored as the byte sequence 0xC2 0xAF.
Is '¯' part of standard ASCII?
No. Standard ASCII covers codes 0–127 only. '¯' is code 175, part of the Latin-1 Supplement (128–255, sometimes called "extended ASCII"). It is a single byte 0xAF in Latin-1 but a multi-byte sequence (0xC2 0xAF) in UTF-8.
