It is listed in the printable character table, as per the ASCII standard, instead of in the control character table. [3]: 223 [10] 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 ...
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). [6] [7]
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
The isolated character 127 (7F hex) also belongs to this group. 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 ...
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.
The following table shows the arrangement of characters, with the hexadecimal value, corresponding ASCII character, binary notation matching the standard dot order, Braille Unicode glyph, and general meaning (the actual meaning may change depending on context). [9] [10]
Similarly, ASCII systems use a zone value of 0011 (hex 3), giving character codes 30 to 39 (hex). For signed zoned decimal values, the rightmost (least significant) zone nibble holds the sign digit, which is the same set of values that are used for signed packed decimal numbers (see above). Thus a zoned decimal value encoded as the hex bytes F1 ...
Percent-encoding a reserved character involves converting the character to its corresponding byte value in ASCII and then representing that value as a pair of hexadecimal digits (if there is a single hex digit, a leading zero is added).
