==ASCII printable characters==
 +
Codes 20<sub>[[hexadecimal|hex]]</sub> to 7E<sub>[[hexadecimal|hex]]</sub>, known as the printable characters, represent letters, digits, [[punctuation marks]], and a few miscellaneous symbols. There are 95 printable characters in total.

Code 20<sub>[[hexadecimal|hex]]</sub>, the [[Space (punctuation)|space character]], denotes the space between words, as produced by the space-bar of a keyboard. Since the space character is considered an invisible graphic (rather than a control character)<ref name="FOOTNOTEMackenzie1980223">[[#CITEREFMackenzie1980|Mackenzie 1980]], p.&nbsp;223.</ref><ref name="RFC20_1968" /> and thus would not normally be visible, it is represented here by [[Unicode]] character U+2420 "␠"; Unicode characters U+2422 "␢" and U+2423 "␣" are also available for use when a visible representation of a space is necessary.
 +
 
 +
Code 7F<sub>[[hexadecimal|hex]]</sub> corresponds to the non-printable "Delete" (DEL) control character and is therefore omitted from this chart; it is covered in the previous section's chart.
 +
 
 +
Earlier versions of ASCII used the up-arrow instead of the [[caret]] (5E<sub>[[hexadecimal|hex]]</sub>) and the left-arrow instead of the [[underscore]] (5F<sub>[[hexadecimal|hex]]</sub>).<ref>[http://www.wps.com/projects/codes/X3.4-1963/index.html ASA X3.4-1963].</ref>

To delete the previous character, one had to back up the paper tape punch, which for mechanical and simplicity reasons was a button on the punch itself and not the keyboard, then type the rubout character. They therefore placed a key producing rubout at the location used on typewriters for backspace. When systems used these terminals and provided command-line editing, they had to use the "rubout" code to perform a backspace, and often did not interpret the backspace character (they might echo "<tt>^H</tt>" for backspace). Other terminals not designed for paper tape made the key at this location produce Backspace, and systems designed for these used that character to back up. Since the delete code often produced a backspace effect, this also forced terminal manufacturers to make any {{keypress|Delete}} key produce something other than the Delete character.</ref>

ASCII printable characters

Codes 20hex to 7Ehex, known as the printable characters, represent letters, digits, punctuation marks, and a few miscellaneous symbols. There are 95 printable characters in total.

Code 20hex, the space character, denotes the space between words, as produced by the space-bar of a keyboard. Since the space character is considered an invisible graphic (rather than a control character)<ref name="FOOTNOTEMackenzie1980223">Mackenzie 1980, p. 223.</ref><ref name="RFC20_1968" /> and thus would not normally be visible, it is represented here by Unicode character U+2420 "␠"; Unicode characters U+2422 "␢" and U+2423 "␣" are also available for use when a visible representation of a space is necessary.

Code 7Fhex corresponds to the non-printable "Delete" (DEL) control character and is therefore omitted from this chart; it is covered in the previous section's chart.

Earlier versions of ASCII used the up-arrow instead of the caret (5Ehex) and the left-arrow instead of the underscore (5Fhex).<ref>ASA X3.4-1963.</ref>
