11、 and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal

12、 with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC

13、 have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the j

14、oint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

20、phic characters identified as Latin/Greek alphabet. This set of coded graphic characters is intended for use in data and text processing applications and also for information interchange. The set contains graphic characters used for general purpose applications in typical office environments in at l

21、east the following languages: English, Greek, and Latin. This set of coded graphic characters may be regarded as a version of an 8-bit code according to ISO/IEC 2022 or ISO/IEC 4873 at level 1. This part of ISO/IEC 8859 may not be used in conjunction with any other parts of ISO/IEC 8859. If coded ch

22、aracters from more than one part are to be used together, by means of code extension techniques, the equivalent coded character sets from ISO/IEC 10367, or their corresponding G1 sets from the ISO International Register of Coded Character Sets to be Used with Escape Sequences, should be used instead

23、 within a version of ISO/IEC 4873 at level 2 or level 3. The coded characters in this set may be used in conjunction with coded control functions selected from ISO/IEC 6429. However, control functions are not used to create composite graphic symbols from two or more graphic characters (see Clause 6)

24、. NOTE ISO/IEC 8859 is not intended for use with Telematic services defined by ITU-T. If information coded according to ISO/IEC 8859 is to be transferred to such services, it will have to conform to the requirements of those services at the access-point. 2 Conformance 2.1 Conformance of information

25、interchange A coded-character-data-element (CC-data- element) within coded information for interchange is in conformance with this part of ISO/IEC 8859 if all the coded representations of graphic characters within that CC-data-element conform to the requirements of Clause 6. 2.2 Conformance of devic

26、es A device is in conformance with this part of ISO/IEC 8859 if it conforms to the requirements of 2.2.1, and either or both of 2.2.2 and 2.2.3. A claim of conformance shall identify the document which contains the description specified in 2.2.1. 2.2.1 Device description A device that conforms to th

27、is part of ISO/IEC 8859 shall be the subject of a description that identifies the means by which the user may supply characters to the device, or may recognize them when they are made available to him, as specified respectively in 2.2.2 and 2.2.3. 2.2.2 Originating devices An originating device shal

28、l allow its user to supply any sequence of characters from those specified in Clause 6, and shall be capable of transmitting their coded representations within a CC-data-element. 2.2.3 Receiving devices A receiving device shall be capable of receiving and interpreting any coded representations of ch

29、aracters that are within a CC-data-element, and that conform to clause 6, and shall make the corresponding characters available to its user in such a way that the user can identify them from among those specified there, and can distinguish them from each other. 3 Normative references The following r

35、on 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 bit combination is used to represent each character. 4.8 graphic symbol: A visual representation of a graphic character or of a control function

36、 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 8-bit code are identified by b 8 , b 7 , b 6 , b 5 , b 4 , b 3 , b 2 , and b 1 , where b 8 is the highest-order, or most-signifi

37、cant bit and b 1 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 to the individual bits: Using these weights, the bit combinations are identified by notations of the form xx/yy, where

38、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 8 to b 1 is as follows: xx is the number represented by b 8 , b 7 , b 6 and b 5 where these bits are given the weights 8, 4, 2, and 1 respectively

39、. yy is the number represented by b 4 , b 3 , b 2 and b 1 where these bits are given the weights 8, 4, 2, and 1 respectively. The bit combinations 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 n

40、umber xx described above, and the number k is the same as the number yy described above. 5.2 Layout of the code table An 8-bit code table consists 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 a

41、re 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 are shown at the top and left edges of the table respectively. The code table positions are also identified by notations of t

42、he 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 respectively. The positions of the code table are in one-to-one correspondence with the bit combinations of the code. The notation

43、 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 meanings This part of ISO/IEC 8859 assigns a unique name and a unique identifier to each graphic character.

ISO/IEC 8859-7:2003(E) ISO/IEC 2003 All rights reserved 3These names and identifiers have been taken from ISO/IEC 10646-1 (E). This part of ISO/IEC 8859 also specifies an acronym for each o

45、f 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 the text. Except for SPACE (SP), NO-BREAK SPACE (NBSP) and SOFT HYPHEN (SHY), this part of ISO/IEC 8859 does not define

46、 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 position of the code table. However, this part, or any other part, of ISO/IEC 8859 does not specify a particular style

47、 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 which consists of the absence of a graphic symbol. 5.3.2 NO-BREAK SPACE (NBSP) A graphic character the visual represen

49、en established within a word. 6 Specification of the coded character set This part of ISO/IEC 8859 specifies 188 characters allocated to the bit combinations of the code table (Table 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 two or more ch
