ASCII 154
Character 154 ()
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 154 (0x9A) 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+009A is a C1 control code. Its UTF-8 encoding is the two-byte sequence 0xC2 0x9A, which is why a raw high byte 0x9A from a legacy Latin-1 file becomes garbled when a program assumes UTF-8.

- ▸Code 154 is in the C1 control range — unassigned in Latin-1, repurposed in Windows-1252.
- ▸A raw byte 0x9A decoded as UTF-8 becomes garbage; specify the correct charset explicitly.
- ▸UTF-8 encoding: 0xC2 0x9A; Unicode code point U+009A.
Unicode & UTF-8 note
In Unicode this is U+009A. In UTF-8 it encodes to the byte sequence 0xC2 0x9A. In legacy Latin-1 (ISO-8859-1) it is a single byte 0x9A, which is why Latin-1 files often appear as mojibake when interpreted as UTF-8.
Frequently asked questions
What character is ASCII code 154?
ASCII code 154 is the character '' (Character 154). In hexadecimal it is 0x9A, in octal 0232, and in binary 10011010.
What is 0x9A in ASCII?
Hexadecimal 0x9A equals decimal 154, which is the character '' (Character 154). To convert hex to ASCII yourself, read the two hex digits as a base-16 number (0x9A = 154) and look up that code point.
How do I write the character with code 154 in code?
In JavaScript use String.fromCharCode(154); in Python use chr(154); in HTML use the numeric entity š. In a URL it is percent-encoded as %9A, and in UTF-8 it is stored as the byte sequence 0xC2 0x9A.
