16、information only.iv blankBSISO/IEC8859-13:1998 BSI 04-1999 1 Introduction ISO/IEC 8859 consists of several parts. Each part specifies a set of up to 191 graphic characters and the coded representation of these characters by means of a single 8-bit byte. Each set is intended for use for a particular

17、group of languages. 1 Scope This part of ISO/IEC8859 specifies a set of 191 coded graphic characters identified as Latin alphabet No. 7. 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 ch

18、aracters used for general purpose applications in typical office environments in at least the following languages: Danish, English, Estonian, Finnish, German, Latin, Latvian, Lithuanian, Norwegian, Polish, Slovene and Swedish. This set of coded graphic characters may be regarded as a version of an 8

19、-bit code according to ISO/IEC2022 or ISO/IEC4873 at level 1. This part of ISO/IEC8859 may not be used in conjunction with any other parts of ISO/IEC8859. Ifcoded characters from more than one part are to be used together, by means of code extension techniques, the equivalent coded character sets fr

20、om ISO/IEC10367 should be used instead within a version of ISO/IEC4873 at level 2 or level 3. The coded characters in this set may be used in conjunction with coded control functions selected from ISO/IEC6429. However, control functions are not used to create composite graphic symbols from two or mo

21、re graphic characters (see clause 6). NOTEISO/IEC8859 is not intended for use with Telematic services defined by ITU-T. If information coded according to ISO/IEC8859 is to be transferred to such services, it will have to conform to the requirements of those services at the access-point. 2 Conformanc

22、e 2.1 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/IEC8859 if all the coded representations of graphic characters within that CC-data-element conform to the requirements of cla

23、use 6. 2.2 Conformance of devices A device is in conformance with this part of ISO/IEC 8859 if it conforms to the requirements of2.2.1, 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 descriptio

24、n A device that conforms to this part of ISO/IEC8859 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 in2.2.2 and 2.2.3. 2.2.2 Originating device

25、s An 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

26、 coded 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 Normativ

30、59 the following definitions apply: 4.1 bit combination an ordered set of bits used for the representation of characters 4.2 byte a bit string that is operated upon as a unitBSISO/IEC8859-13:1998 2 BSI 04-1999 4.3 character a member of a set of elements used for the organization, control, or represe

31、ntation of data 4.4 code table a table showing the characters allocated to each bit combination in a code 4.5 coded character set; 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 4.6 coded-c

32、haracter-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 identified standards for coded character sets 4.7 graphic character a character, other than a control funct

33、ion, that has a visual representation normally handwritten, printed or displayed, and that has a coded representation consisting of one or more bit combinations NOTEIn ISO/IEC 8859 a single bit combination is used to represent each character. 4.8 graphic symbol a visual representation of a graphic c

34、haracter 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 combinations of the 8-bit code areidentified by b 8 , b 7 , b 6 , b 5 , b 4 , b 3 , b 2 , and b 1 , where b 8is the

35、highest-order, or most-significant bit and b 1is 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 notati

36、ons 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 bitsb 8to b 1is as follows: xx is the number represented by b 8 , b 7 , b 6andb 5where these bits are given the weights 8, 4

37、, 2, and 1 respectively. yy is the number represented by b 4 , b 3 , b 2andb 1where 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

38、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 consists of 256 positions arranged in 16 columns and 16 rows. The columns and the rows are numbered 00 to 15. In hexadecimal notation the columns

39、 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 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

40、 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 table respectively. The positions of the code table are in one-to-one correspondence with the bit combinations of the cod

41、e. 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/IEC8859 assigns a unique name and a unique identifier to each graphic character. These names and identifiers have been tak

42、en from ISO/IEC 10646-1 (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 the text. Except for SPACE (

43、SP), NO-BREAK SPACE (NBSP) and SOFT HYPHEN (SHY), this part of ISO/IEC8859 does not define and does not restrict the meanings of graphic characters.

44、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/IEC8859 does not specify a particular style or font design for imaging graphic characters. Annex B of ISO/IEC10367 gives further information on this subject

45、. 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 representation of which consists of the absence of a graphic symbol, for use when a line break is to be prevented in the t

46、ext as presented. 5.3.3 Soft hyphen (SHY) A graphic character that is 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 characterset This part of ISO/IEC8859 specifies 191 cha

47、racters allocated to the bit combinations of the code table (Table 2). None of these characters are combining characters. NOTECombining characters are described in ISO/IEC2022:1994 subclause 6.3.3. Control functions, such as BACKSPACE or CARRIAGE RETURN, shall not be used to create composite graphic

48、 symbols, which are made up from the graphic representations of two or more characters. 6.1 Characters of the set and their coded representation See Table 1.
