Names follow the ANSI X3.4 / Unicode C0 control identifiers. This table covers 7-bit ASCII only, not any 8-bit extension or code page.

How it works

US-ASCII (ANSI X3.4 / ISO/IEC 646), which is also the first 128 code points of Unicode: the C0 control characters (0–31), the printable characters (32–126), and DEL (127). Each row shows the decimal, two-digit hexadecimal, three-digit octal, and eight-bit binary value, the abbreviation or glyph, the long name for control characters, and the C-style escape sequence where one exists. Filter by any of those — a number, `0x0A`, `LF`, `\n`, or a glyph. Control-character names are the standard identifiers and are shown in English in both languages.
