ASCII 131
Character 131 ()
Latin-1 Supplement
Unassigned in Latin-1 / part of the C1 control block. Not used in modern text encoding; browsers accept these code points but they carry no display glyph.
Common uses & context
Decimal 131 (0x83) falls in the C1 control range (128–159). In the Latin-1 (ISO-8859-1) encoding these code points are unassigned control positions with no visible glyph, and in Windows-1252 many of them were repurposed for typographic characters like curly quotes and the em dash. That mismatch is a classic cause of mojibake: a byte stored as Windows-1252 but decoded as Latin-1 (or UTF-8) shows the wrong character or a replacement box.
In modern Unicode, U+0083 is a C1 control code. Its UTF-8 encoding is the two-byte sequence 0xC2 0x83, which is why a raw high byte 0x83 from a legacy Latin-1 file becomes garbled when a program assumes UTF-8.

ƒ <!-- numeric entity (no named entity for this character) -->Programming notes
- ▸Code 131 is in the C1 control range — unassigned in Latin-1, repurposed in Windows-1252.
- ▸A raw byte 0x83 decoded as UTF-8 becomes garbage; specify the correct charset explicitly.
- ▸UTF-8 encoding: 0xC2 0x83; Unicode code point U+0083.
Unicode & UTF-8 note
In Unicode this is U+0083. In UTF-8 it encodes to the byte sequence 0xC2 0x83. In legacy Latin-1 (ISO-8859-1) it is a single byte 0x83, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.
Frequently asked questions
What character is ASCII code 131?
ASCII code 131 is the character '' (Character 131). In hexadecimal it is 0x83, in octal 0203, and in binary 10000011.
What is 0x83 in ASCII?
Hexadecimal 0x83 equals decimal 131, which is the character '' (Character 131). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0x83 = 131) and look up that code point.
How do I write the character with code 131 in code?
In JavaScript use String.fromCharCode(131); in Python use chr(131); in HTML use the numeric entity ƒ. In a URL it is percent-encoded as %83, and in UTF-8 it is stored as the byte sequence 0xC2 0x83.
