ASCII Table

By Xah Lee. Date: 2010-09-03. Last updated: 2021-07-16.

ASCII characters are Unicode characters with codepoint from 0 to 127, inclusive. They are mostly the symbols you see on computer keyboard.

Codepoint 0 to 31, and 127, are control characters or non-printables characters. (including space, tab, newline characters). Also, codepoint 127 is DEL, usually the signal sent by the Backspace ⌫ key or Delete ⌦ on keyboard.

Unicode Symbol Representation

Unicode has glyphs to represent non-printables ASCII characters.

Representation of Unprintable Characters

Unprintable Characters can be represented in multiple ways. By decimal, hexadecimal, by standardized abbrev, or Unicode glyph, or caret notation, and in programing languages some have C escape syntax in string.

Caret notation is heavily used in emacs. [see Emacs: Newline Representation ^M ^J ^L]

Non-printable ASCII is heavily used in unix terminal. See: Linux: Terminal Control Sequence Keys

Stack Overflow offline screenshot — Stack Overflow Offline Page (2011-08-06T13:49:05-07:00) showing unprintable ASCII characters, by caret notation. Note that the ^M represents the ASCII 13, carriage return. Any ^ followed by a letter represents a ASCII non-printable char. The ^@ is ASCII 0, the Null character.
