Code 7F hex corresponds to the non-printable "delete" (DEL) control character and is listed in the control character table. Earlier versions of ASCII used the up arrow instead of the caret (5E hex) and the left arrow instead of the underscore (5F hex). [6] [50]
Table rows 2 to 7, codes 32 to 126 (20 hex to 7E hex), are the standard ASCII printable characters. Table rows 8 to 10, codes 128 to 175 (80 hex to AF hex), are a selection of international text characters. Table rows 11 to 13, codes 176 to 223 (B0 hex to DF hex), are box drawing and block characters. This block is arranged so that characters ...
The following table shows the arrangement of characters, with the hex value, corresponding ASCII character, Braille 6-bit codes (dot combinations), Braille Unicode glyph, and general meaning (the actual meaning may change depending on context).

In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
However, it consists purely or largely of information which is better suited to representation in wikitext (possibly using MediaWiki's special syntax for tables, math, or music). This will make the information easier to edit, as well as make it accessible to users of screen readers and text-based browsers.
Forty-four characters are marked as Hex_Digit. The ones in the Basic Latin block are also marked as ASCII_Hex_Digit. Unicode has no separate characters for hexadecimal values. A consequence is, that when using regular characters it is not possible to determine whether hexadecimal value is intended, or even whether a value is intended at all.
It is a superset of ASCII, and has most of the characters that are in ISO-8859-1 and all the extra characters from Windows-1252, but in a totally different arrangement. The few printable characters that are in ISO/IEC 8859-1, but not in this set, are often a source of trouble when editing text on Web sites using older Macintosh browsers ...
