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 .

Shift JIS is an extension of the single-byte encoding JIS X 0201:1997, that uses unassigned code points in JIS X 0201 to encode the double-byte JIS X 0208:1997 character set. The lead bytes for the double-byte characters are "shifted" around the 64 halfwidth katakana characters in the single-byte range 0xA1 to 0xDF .
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
The term DBCS traditionally refers to a character encoding where each graphic character is encoded in two bytes.. In an 8-bit code, such as Big-5 or Shift JIS, a character from the DBCS is represented with a lead (first) byte with the most significant bit set (i.e., being greater than seven bits), and paired up with a single-byte character-set (SBCS).
For example, the PDP-10 byte pointer contained the size of the byte in bits (allowing different-sized bytes to be accessed), the bit position of the byte within the word, and the word address of the data. Instructions could automatically adjust the pointer to the next byte on, for example, load and deposit (store) operations.
When an aggregate is entirely composed of the same type of primitive, the aggregate may be called an array; in a sense, a multi-byte word primitive is an array of bytes, and some programs use words in this way. A pointer is a programming concept used in computer science to reference or point to a memory location that stores a value or an object.
However, the number of characters in Japanese is many more than 256 and thus cannot be encoded using a single byte - Japanese is thus encoded using two or more bytes, in a so-called "double byte" or "multi-byte" encoding. Problems that arise relate to transliteration and romanization, character encoding, and input of Japanese text.
