1、INTERNATIONAL STANDARD ISOAEC 8859-4 First edition 1998-07-01 Information technology - 8-bit single-byte coded graphic character sets - Part 4: Latin alphabet No. 4 Technologies de /information - Jeux de caractkres graphiques cod code: A set of unambiguous rules that establishes a character set and
2、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 iden
3、tified 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 b
4、it combination is used to represent each character. 4.8 graphic symbol: A visual representation of a graphic character or of a control function. 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 com
5、binations of the 8-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, is the lowest-order, or least-significant bit. The bit combinations may be interpreted to represent numbers in binary notation by attributing the following weights
6、to the individual bits: Bit b8 b7 b6 bs b4 b3 b2 b, 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 combinati
7、ons consisting of the bits b, to b, is as follows: - xx is the number represented by b, b, b, and b, where these bits are given the weights 8, 4, 2, and 1 respectively. - yy is the number represented by b, b, b, and b, where these bits are given the weights 8, 4, 2, and 1 respectively. The bit combi
8、nations are also identified by notations 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 8-bit code table cons
9、ists of 256 positions arranged in 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 nu
10、mber. The column and row numbers 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 a
11、nd right edges of the table respectively. 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/yy, or of the form hk, is the same as that of the corresponding bit combination. 5.3 Names and meani
12、ngs This part of ISO/IEC 8859 assigns a unique name and a unique identifier to each graphic character. These names and identifiers have been taken from 2 Copyright American National Standards Institute Provided by IHS under license with ANSINot for ResaleNo reproduction or networking permitted witho
13、ut license from IHS-,-,-0 ISO/IEC ISO/IEC 10646-l (E). This part of ISO/IEC 8859 also specifies an acronym for each of the characters SPACE, NO-BREAK SPACE and SOFT HYPHEN. For acronyms only Latin capital letters A to Z are used. It is intended that the acronyms be retained in all translations of th
14、e text. Except for SPACE (SP), NO-BREAK SPACE (NBSP) and SOFT HYPHEN (SHY), this part of ISO/IEC 8859 does not define and does not restrict the meanings of graphic characters. This part of ISO/IEC 8859 specifies a graphic symbol for each graphic character. This symbol is shown in the corresponding p
15、osition of the code table. However, this part, or any other part, of ISO/IEC 8859 does not specify a particular style or font design for imaging graphic characters. Annex B of ISO/IEC 10367 gives further information on this subject. 5.3.1 SPACE (SP) A graphic character the visual representation of w
16、hich consists of the absence of a graphic symbol. 5.3.2 NO-BREAK SPACE (NBSP) A graphic character the visual representation of which consists of the absence of a graphic symbol, for use when a line break is to be prevented in the text as presented. 5.3.3 SOFT HYPHEN (SHY) A graphic character that is
17、 imaged by a graphic symbol identical with, or similar to, that representing HYPHEN, for use when a line break has been established within a word. 6 Specification of the coded character set This part of ISO/IEC 8859 specifies 191 characters allocated to the bit combinations of the code table (table
18、2). None of these characters are combining characters. NOTE - Combining characters are described in ISO/IEC 2022:1994 subclause 6.3.3. Control functions, such as BACKSPACE or CARRIAGE RETURN, shall not be used to create composite graphic symbols, which are made up from the graphic representations of
19、 two or more characters. 6.1 Characters of the set and their coded representation See table 1.
