7、for ResaleNo reproduction or networking permitted without license from IHS-,-,-ISO/IEC 10367:1991 Foreword IS0 (the International organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that

8、are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other internati

9、onal organizations, governmental and non- governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTCl. Draft International Standards adopted by the joint technical committee are

10、circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 10367 was prepared by Joint Technical Committee ISO/IEC JTCI, Information technology. Annexes A and C form an int

11、egral part of this International Standard. Annex B is for information only. iv Copyright American National Standards Institute Provided by IHS under license with ANSINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-ISO/IEC 10367:1991 Introduction In the course of th

12、e past years two different g-bit codes were developed by ISO/IEC/JTCl/SCZ. An International Standard, ISO/IEC 6937, was developed with a view to satisfying the needs of CCITT-defined Telematic services: Teletex and Videotex. It is based on a primary and supplementary set of graphic characters, the l

13、atter containing a series of so-called non-spacing diacritical marks for the generation of accented letters. Thus, the coded representation of a graphic character may consist of one or more bit combinations. The standard specifies the allowed repertoire of 333 characters. ISO/IEC 6937 is applicable

14、not only to 8-bit coding but also to 7-bit coding. A family of S-bit code tables, IS0 8859, was also developed to satisfy a need for single-byte coded graphic characters in particular in data processing applications. It consists of several parts, each specifying an 8-bit single- byte coded graphic c

15、haracter set of up to 191 characters. The selection of characters for each set is such that it satisfies the needs of several languages of a large, relatively coherent, geographical area. The different parts of 1SO 8859 cover not only the Latin script but also the Arabic, Cyrillic, Greek and Hebrew

16、scripts. Many applications need a code structure which permits more than one script to be represented in information interchange, for example Latin Alphabet No. 1 (“Western” Europe) with the Greek script or Latin Alphabet No. 2 (“Eastern” Europe) with the Cyrillic script. For this purpose ISO/IEC 48

17、73 is suitable since it allows up to 382 graphic characters grouped in four G sets, by using a small selection of the facilities offered by IS0 2022. Within this structure the graphic character sets from the various parts of IS0 8859 may be used in conjunction with each other. Since some characters

18、appear in more than one of these sets, rules are needed to avoid violation of the principle of one-to-one relationship between a character and its coded representation when such sets are used together. The new version of ISO/lEC 4873 (3rd edition of 1991) contains such rules. In a similar way ISO/IE

19、C 6937 may be used in conjunction with additional non-Latin graphic character sets taken from the parts of IS0 8859. Thus this International Standard specifies a collection of coded graphic character sets usable within the structure of ISO/IEC 4873. Copyright American National Standards Institute Pr

21、 a unique coded graphic character set for use as GO set and a series of coded graphic character sets of up to 96 characters for use as the Cl, G2 and G3 sets in versions of lSO/lEC 4873. All sets specified in this International Standard are shown as elements of an g-bit code. These sets are intended

22、 for use in data and text processing applications and may also be used for information interchange. They contain graphic characters used for general purpose applications in typical office environments. This International Standard does not specify the control functions to be allocated to the CO and C

23、l sets of versions of ISO/IEC 4873. ISO/IEC 6429 specifies these control functions; the required control functions shall be selected from that International Standard depending on the application considered. 2 Conformance 2.1 Conformance of information interchange A coded-character-data-element (CC-d

24、ata-element) within coded information for interchange is in conformance with this International Standard if all the coded representations of characters within that CC-data-element conform to the requirements of clause 6 and of ISOllEC 4873. A claim of conformance shall identify the selected characte

25、r sets. 2.2 Conformance of devices A device is in conformance with this International Standard 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, and shall identify

26、the selected character sets. 2.2.1 Device description A device that conforms to this International Standard 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 r

27、espectively in 2.2.2 and 2.2.3. 2.2.2 Originating devices An originating device shall allow its user to supply any sequence of characters from the selected character sets, and shall be capable of transmitting their coded representations within a CC-data-element. 2.2.3 Receiving devices A receiving d

28、evice shall be capable of receiving and interpreting any coded representations of characters that are within a CC-data-element, and that conform to 2.1, and shall make the corresponding characters available to its user in such a way that the user can identify them from among those from the selected

29、character sets, and can distinguish them from each other.

This entity may be a process such as an application program if the “device ” is a code convertor or a gateway function, for example. 2. The characters, as supplied by the user or made available to him, may be in th

44、e form of codes local to the device, or of non- conventional visible representations. provided that 2.2 above is satisfied. 5 Notation, code tables and names Each coded character set is represented as a part of an S-bit code table. These sets are identical with those of the International Register wh

45、ere they are shown in a 7-bit environment. 5.1 Notation The bits of the bit combination of the S-bit code are identified by b8, b7, b6, b5, b4, b3, b2 and bl, where b8 is the highest-order, or most-significant bit and bl is the lowest-order, or least-significant bit. The bit combinations may be inte

46、rpreted to represent integers in the range 0 to 255 in binary notation by attributing the following weights to the individual bits. Bit b8 b7 b6 b5 b4 b3 b2 bl Weight 128 64 32 16 8 4 2 1 Using these weights, these 8-bit combinations represent numbers in the range 0 to 255. The bit combinations are

47、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 b8 to bl is as follows: - xx is the number represented by b8, b7, b6 and b5 where these bits are gi

48、ven the weights 8, 4, 2 and 1 respectively; - yy is the number represented by b4, b3, b2 and bl where these bits are given the weights 8, 4, 2 and 1 respectively. The notations of the form xx/yy are the same as those used to identify code table positions, where xx is the column number and yy is the
