ASCII Tables Codes: (0 - 31, 127) (32 - 47) (48 - 63) (64 - 79) (80 - 95) (96 - 111) (112 - 126)

These tables show the 128-character ASCII set for U.S. English systems. Most of the characters in code range 32..126 (the only codes for which ASCII specifies displayable symbols) will be the same on non-U.S. systems. The symbols associated with all other codes vary from font to font, as well as from country to country.

 

For more details on ASCII, character sets, and key codes, see the general information topic on ASCII, Key Codes, and ANSI X3.64 Commands.
