ASCII reserves the first 32 code points (numbers 0–31 decimal) and the last one (number 127 decimal) for control characters. These are codes intended to control peripheral devices (such as printers ), or to provide meta-information about data streams, such as those stored on magnetic tape.

Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

Code points are commonly used in character encoding, where a code point is a numerical value that maps to a specific character.In character encoding code points usually represent a single grapheme—usually a letter, digit, punctuation mark, or whitespace—but sometimes represent symbols, control characters, or formatting.

HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. 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 row number and a cell number (each numbered from 1 to 94, for a standard JIS X 0208 code) form a kuten point, which is used to represent double-byte code points. A code number or kuten number ( 区点番号 , kuten bangō ) is expressed in the form "row-cell", the row and cell numbers being separated by a hyphen .
In the above, is a two-byte Shift_JIS-2004 sequence, is the plane (面, men, surface) number (1 or 2), is the row (区, ku, ward) number (1-94) and is the cell (点, ten, point) number (1-94). The ku and ten numbers are equivalent to j 1 − 32 {\displaystyle j_{1}-32} and j 2 − 32 {\displaystyle j_{2}-32} respectively, where j 1 j 2 ...
