11、ization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the res
12、pective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and nongovernmental, in liaison with IS0 and IEC, also take part in the work. In the field of informat
13、ion technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTCI . Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bod
14、ies casting a vote. International Standard ISO/IEC 8859-8 was prepared by Joint Technical Committee ISOAEC JTC 1, Information technology, Subcommittee SC 2, Coded character sets. This edition cancels and replaces IS0 8859-8:1988 which has been technically revised. ISOAEC 8859 consists of the followi
15、ng parts, under the general title Information technology - 8-bit single-byte coded graphic character sets: - Part I: Latin alphabet No. I - Part 2: Latin alphabet No. 2 - Part 3: Latin alphabet No. 3 - Part 4: Latin alphabet No. 4 - Part 5: Latin/CyrilIic alphabet - Part 6: LatMArabc alphabet - Fart

20、phic character sets - Part 8: LatidHebrew alphabet 1 Scope This part of ISO/IEC 8859 specifies a set of 155 coded graphic characters identified as Latin/Hebrew alphabet. This set of coded graphic characters is intended for use in data and text processing applications and also for information interch
21、ange. The set contains graphic characters used for general purpose applications in typical office environments in at least the following languages: English, Hebrew, Latin. It is not intended for pointed Hebrew. This set of coded graphic characters may be regarded as a version of an 8-bit code accord
22、ing to ISO/IEC 2022 or ISO/IEC 4873 at level i. This part of ISO/IEC 8859 may not be used in conjunction with any other parts of ISO/IEC 8859. If coded characters from more than one part are to be used together, by means of code extension techniques, the equivalent coded character sets from ISOIEC 1
23、0367 should be used instead 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 ISOAEC 6429. However, control functions are not used to create composite graphic symbols from two or more graphic
24、 characters (see clause 6). 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
25、 Conformance of information 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
26、6. 2.2 Conformance of devices A device is in conformance with this part of ISOAEC 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
27、device that conforms to this part of ISOAEC 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 A
28、n originating device shall 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 co
29、ded representations of characters 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 r

33、logy - Character code structure and extension techniques. ISOAEC 4873:1991, Information technology - IS0 code: A set of unambiguous rules that establishes a character set and the one-to-one relationship between the characters of the set and their bit combinations. 4.7 coded-character-data-element (C
34、C-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 identified standards for coded character sets. 4.8 directional character properties: A set of mutually exclusive properties which
35、 may qualify the members of a character set. These properties are used by algorithms which transform text from processing sequence into presentation sequence. Examples of values for directional character properties a re “rig h t-to- I eft“, “ left-to- ri g h t I, “dig it “, “nu me ric sepa rato r“,
36、“ne ut ra I“. 4.9 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 ISOIEC 8859 a single bit combination is used to repr
37、esent each character. O ISOAEC 4.10 graphic symbol: A visual representation of a graphic character or of a control function. 4.1 1 implicit directionality: A text presentation method in which the direction is determined by an algorithm. The algorithm is based on the directional character properties
38、of the character, its position relative to the preceding and following character and to the primary direction. 4.12 left-to-right character: A character specific to a script written from left to right like the Latin script or the Greek script. Typical examples are the letters A-Z. 4.13 position: Tha
39、t part of a code table identified by its column and row coordinates. 4.14 right-to-left character: A character specific to a script written from right to left like the Arabic script or the Hebrew script. Typical examples are the letters of the Hebrew alphabet. 5 Notation, code table and names 5.1 No

43、ranged in 16 columns and 16 rows. The columns and the rows are numbered O0 to 15. In hexa- decimal notation the columns and the rows are numbered O 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
44、 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 and right edges of the ta
45、ble 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 meanings This part of ISO/IEC
46、 8859 assigns a unique name and a unique identifier to each graphic character. These names and identifiers have been taken from ISO/IEC 10646-1 (E). This part of ISO/IEC 8859 also specifies an acronym for each of the characters LEFT-TO-RIGHT MARK and RIGHT-TO-LEFT MARK. For acronyms only Latin capit
47、al 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 MARK (LRM) and RIGHT-TO-LEFT MARK (RLM), this part of ISO/IEC 8859 does not define and does not restrict the meanings of graphic characters. This part of IS
48、O/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 ISOAEC 8859 does not specify a particular style or font design for imaging graphic characters. Annex B of ISO/IEC 10367 gi
