1、INTERNATIONAL STANDARD lSO/lEC 8859-l First edition 1998-04-I 5 Information technology - 8-bit single-byte coded graphic character sets - Part 1: Latin alphabet No. 1 Technologies de /information - Jeux de caracteres graphiques cod code: A set of unambiguous rules that establishes a character set an
2、d the one-to-one relationship between the characters of the set and their bit combinations. 4.6 coded-character-data-element (CC-data- element): An element of interchanged information that is specified to consist of a sequence of coded representations of characters, in accordance with one or more id
3、entified standards for coded character sets. 4.7 graphic character: A character, other than a control function, that has a visual representation normally handwritten, printed or displayed, and that has a coded representation consisting of one or more bit combinations. NOTE - In ISO/IEC 8859 a single
4、 bit combination is used to represent each character. 4.8 graphic symbol: A visual representation of a graphic character or of a control function. The bit combinations may be interpreted to represent numbers in binary notation by attributing the following weights to the individual bits: Bit b8 b7 b6
5、 b5 b4 b3 b2 bl Weight 128 64 32 16 8 4 2 1 Using these weights, the bit combinations are identified by notations of the form xx/yy, where xx and yy are numbers in the range 00 to 15. The correspondence between the notations of the form xx/yy and the bit combinations consisting of the bits b, to b,
6、is as follows: - xx is the number represented by b,s, b, b, and b, where these bits are given the werghts 8, 4, 2, and 1 respectively. - yy is the number represented by bp, b, b, and b, where these bits are given the weights 8, 4, 2, and 1 respectively. The bit combinations are also identified by no
7、tations of the form hk, where h and k are numbers in the range 0 to F in hexadecimal notation. The number h is the same as the number xx described above, and the number k the same as the number yy described above. 5.2 Layout of the code table An g-bit code table consists of 256 positions arranged in
8、 16 columns and 16 rows. The columns and the rows are numbered 00 to 15. In hexa- decimal notation the columns and the rows are numbered 0 to F. The code table positions are identified by notations of the form xx/yy, where xx is the column number and yy is the row number. The column and row numbers
9、are shown at the top and left edges of the table respectively. The code table positions are also identified by notations of the form hk, where h is the column number and k is the row number in hexadecimal notation. The column and row numbers are shown at the bottom and right edges of the table respe
10、ctively. 4.9 position: That part of a code table identified by its column and row coordinates. 5 Notation, code table, and names 5.1 Notation The bits of the bit combinations of the g-bit code are identified by b, b, b, b, b, b, b, and b, where b, is the highest-order, or most-significant bit and b,
11、 is the lowest-order, or least-significant bit. The positions of the code table are in one-to-one correspondence with the bit combinations of the code. The notation of a code table position, of the form xx it is specified in other International Standards, for example ISOAEC 6429. Table 2 - Code tabl
