National bodies that aremembers of ISO or IEC participate in the development ofInternational Standards through technical committees es

Other international organizations, governmental andnongovernmental, in liaison with ISO and IEC, also take part in thework.In the fie

12、lowing parts, under the general titleInformation technology 8-bit single-byte coded graphic charactersets: Part 1: Latin alphabet No. 1 Part 2: Latin alphabet No. 2 Part 3: Latin alphabet No. 3 Part 4: Latin alphabet No. 4 Part 5: Latin/Cyrillic alphabet Part 6: Latin/Arabic alphabet Part 7: Latin/G

Each part specifies a set ofup to 191 graph
14、ic characters and the coded representation of thesecharacters by means of a single 8-bit byte. Each set is intended foruse for a particular group of languages.ivINTERNATIONAL STANDARD ISO/IEC ISO/IEC 8859-8:1999 (E)Information technology 8-bit single-byte coded graphic character sets Part 8: Latin/H
15、ebrew alphabet1 ScopeThis part of ISO/IEC 8859 specifies a set of 155coded graphic characters identified as Latin/Hebrewalphabet.This set of coded graphic characters is intended foruse in data and text processing applications andalso for information interchange.The set contains graphic characters us
16、ed forgeneral purpose applications in typical officeenvironments in at least the following languages:English, Hebrew, Latin.It is not intended for pointed Hebrew.This set of coded graphic characters may beregarded as a version of an 8-bit code according toISO/IEC 2022 or ISO/IEC 4873 at level 1.This
17、 part of ISO/IEC 8859 may not be used inconjunction with any other parts of ISO/IEC 8859.If coded characters from more than one part are tobe used together, by means of code extensiontechniques, the equivalent coded character setsfrom ISO/IEC 10367 should be used instead withina version of ISO/IEC 4
18、873 at level 2 or level 3.The coded characters in this set may be used inconjunction with coded control functions selectedfrom ISO/IEC 6429. However, control functions arenot used to create composite graphic symbols fromtwo or more graphic characters (see clause 6).NOTE ISO/IEC 8859 is not intended
19、for use withTelematic services defined by ITU-T. If information codedaccording to ISO/IEC 8859 is to be transferred to suchservices, it will have to conform to the requirements ofthose services at the access-point.2 Conformance2.1 Conformance of information interchangeA coded-character-data-element

28、nstrings of characters with left-to-right and right-to-left directions.4.2 bit combination: An ordered set of bits usedfor the representation of characters.4.3 byte: A bit string that is operated upon as a unit.4.4 character: A member of a set of elementsused for the organization, control, or repres
29、entationof data.4.5 code table: A table showing the charactersallocated to each bit combination in a code.4.6 coded character set; code: Asetofunambiguous rules that establishes a character setand the one-to-one relationship between thecharacters of the set and their bit combinations.4.7 coded-chara
30、cter-data-element (CC-data-element): An element of interchanged informationthat is specified to consist of a sequence of codedrepresentations of characters, in accordance withone or more identified standards for codedcharacter sets.4.8 directional character properties: A set ofmutually exclusive pro
31、perties which may qualify themembers of a character set. These properties areused by algorithms which transform text fromprocessing sequence into presentation sequence.Examples of values for directional characterproperties are “right-to-left“, “left-to-right“, “digit“,“numeric separator“, “neutral“.
32、4.9 graphic character: A character, other than acontrol function, that has a visual representationnormally handwritten, printed or displayed, and thathas a coded representation consisting of one ormore bit combinations.NOTE In ISO/IEC 8859 a single bit combination is usedto represent each character.
33、4.10 graphic symbol: A visual representation ofa graphic character or of a control function.4.11 implicit directionality: A text presentationmethod in which the direction is determined by analgorithm. The algorithm is based on the directionalcharacter properties of the character, its positionrelativ

Typical examples are theletters AZ.4.13 position: That part of a code table identifiedby its colum
35、n and row coordinates.4.14 right-to-left character: A character specificto a script written from right to left like the Arabicscript or the Hebrew script. Typical examples arethe letters of the Hebrew alphabet.5 Notation, code table and names5.1 NotationThe bits of the bit combinations of the 8-bit
36、code areidentified by b8,b7,b6,b5,b4,b3,b2, and b1, whereb8is the highest-order, or most-significant bit and b1is the lowest-order, or least-significant bit.The bit combinations may be interpreted torepresent numbers in binary notation by attributingthe following weights to the individual bits:Using
37、 these weights, the bit combinations areBit b8b7b6b5b4b3b2b1Weight 128 64 32 16 8 4 2 1identified by notations of the form xx/yy, where xxand yy are numbers in the range 00 to 15. Thecorrespondence between the notations of the formxx/yy and the bit combinations consisting of the bitsb8to b1is as fol
38、lows: xx is the number represented by b8,b7,b6andb5where these bits are given the weights 8, 4, 2,and 1 respectively. yy is the number represented by b4,b3,b2andb1where these bits are given the weights 8, 4, 2,and 1 respectively.The bit combinations are also identified by notationsof the form hk, wh
39、ere h and k are numbers in therange 0 to F in hexadecimal notation. The numberh is the same as the number xx described above,and the number k the same as the number yydescribed above.2 ISO/IEC ISO/IEC 8859-8:1999 (E)5.2 Layout of the code tableAn 8-bit code table consists of 256 positionsarranged in
40、 16 columns and 16 rows. The columnsand the rows are numbered 00 to 15. In hexa-decimal notation the columns and the rows arenumbered 0 to F.The code table positions are identified by notationsof the form xx/yy, where xx is the column numberand yy is the row number. The column and rownumbers are sho
41、wn at the top and left edges of thetable respectively. The code table positions arealso identified by notations of the form hk, where his the column number and k is the row number inhexadecimal notation. The column and rownumbers are shown at the bottom and right edges ofthe table respectively.The p
42、ositions of the code table are in one-to-onecorrespondence with the bit combinations of thecode. The notation of a code table position, of theform xx/yy, or of the form hk, is the same as that ofthe corresponding bit combination.5.3 Names and meaningsThis part of ISO/IEC 8859 assigns a unique namean
43、d a unique identifier to each graphic character.These names and identifiers have been taken fromISO/IEC 10646-1 (E). This part of ISO/IEC 8859also specifies an acronym for each of the charactersSPACE, NO-BREAK SPACE, SOFT HYPHEN,LEFT-TO-RIGHT MARK and RIGHT-TO-LEFTMARK. For acronyms only Latin capit
44、al letters A toZ are used. It is intended that the acronyms beretained in all translations of the text.Except for SPACE (SP), NO-BREAK SPACE(NBSP), SOFT HYPHEN (SHY), LEFT-TO-RIGHTMARK (LRM) and RIGHT-TO-LEFT MARK (RLM),this part of ISO/IEC 8859 does not define and doesnot restrict the meanings of g
45、raphic characters.This part of ISO/IEC 8859 specifies a graphicsymbol for each graphic character. This symbol isshown in the corresponding position of the codetable. However, this part, or any other part, ofISO/IEC 8859 does not specify a particular style orfont design for imaging graphic characters
46、. AnnexB of ISO/IEC 10367 gives further information on thissubject.5.3.1 SPACE (SP)A graphic character the visual representation ofwhich consists of the absence of a graphic symbol.5.3.2 NO-BREAK SPACE (NBSP)A graphic character the visual representation ofwhich consists of the absence of a graphic s
47、ymbol,for use when a line break is to be prevented in thetext as presented.5.3.3 SOFT HYPHEN (SHY)A graphic character that is imaged by a graphicsymbol identical with, or similar to, that representingHYPHEN, for use when a line break has beenestablished within a word.5.3.4 LEFT-TO-RIGHT MARK (LRM)A
48、graphic character the visual representation ofwhich consists of the absence of a graphic symbol,which acts like a left-to-right character in a bi-directional text (such as LATIN SMALL LETTER A).5.3.5 RIGHT-TO-LEFT MARK (RLM)A graphic character the visual representation ofwhich consists of the absenc
49、e of a graphic symbol,which acts like a right-to-left character in a bi-directional text (such as HEBREW LETTER ALEF).6 Specification of the coded character setThis part of ISO/IEC 8859 specifies 155 charactersallocated to the bit combinations of the code table(table 2).Control functions, such as BACKSPACE orCARRIAGE RETURN, shall not be used to createcomposite
