Each part specifies a set of up to191 graphic characters and the coded representation of these characters by means of a single8-bit byte. Each set is i

17、ntended for use for a particular group of languages. 1 Scope This part of ISO/IEC8859 specifies a set of191 coded graphic characters identified as Latin alphabet No. 2. This set of coded graphic characters is intended for use in data and text processing applications and also for information intercha

18、nge. The set contains graphic characters used for general purpose applications in typical office environments in at least the following languages: Albanian, Croat, Czech, English, German, Hungarian, Latin, Polish, Romanian, Slovak, Slovene and Sorbian. This set of coded graphic characters may be reg

19、arded as a version of an8-bit code according to ISO/IEC2022 or ISO/IEC4873 at level1. This part of ISO/IEC8859 may not be used in conjunction with any other parts of ISO/IEC8859. If coded characters from more than one part are to be used together, by means of code extension techniques, the equivalen

20、t coded character sets from ISO/IEC10367 should be used instead within a version of ISO/IEC4873 at level2 or level3. 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 graphi

21、c symbols from two or more graphic characters (seeclause6). 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 acce

22、ss-point. 2 Conformance 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 t

23、he requirements of clause6. 2.2 Conformance of devices A device is in conformance with this part of ISO/IEC8859 if it conforms to the requirements of2.2.1, and either or both of2.2.2 and2.2.3. A claim of conformance shall identify the document which contains the description specified in2.2.1. 2.2.1

24、Device description 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 and2.2.3. 2.2.2 Or

25、iginating devices An originating device shall allow its user to supply any sequence of characters from those specified in clause6, 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 i

26、nterpreting any coded representations of characters that are within a CC-data-element, and that conform to clause6, 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 oth

30、 of ISO/IEC8859 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/IEC 8859-2:1999 2 BSI 02-2000 4.3 character a member of a set of elements used for the organization, contro

31、l, or representation 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 combination

32、s 4.6 coded-character-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

33、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 NOTEIn ISO/IEC8859 a single bit combination is used to represent each character. 4.8 graphic symbol a visual representation of

34、 a graphic character 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 the8-bit code are identified by b 8 , b 7 , b 6 , b 5 , b 4 , b 3 , b 2 , and b 1 , wher

35、e b 8is the 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 identifi

36、ed by notations of the form xx/yy, where xx and yy are numbers in the range00 to15. The correspondence between the notations of the formxx/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 6and b 5where these bits are given the we

37、ights8, 4, 2, and1 respectively. yy is the number represented by b 4 , b 3 , b 2andb 1where these bits are given the weights 8, 4, 2, and1 respectively. The bit combinations are also identified by notations of the form hk, where h and k are numbers in the range0 to F in hexadecimal notation. The num

38、ber h 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 of256 positions arranged in16 columns and16 rows. The columns and the rows are numbered00 to15. In hexadecimal notation the column

39、s and the rows are numbered0 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.

42、e name and a unique identifier to each graphic character. These names and identifiers have been taken from ISO/IEC10646-1 (E). This part of ISO/IEC8859 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.

43、 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/IEC8859 does not define and does not restrict the meanings of graphic characters. This part of ISO/IEC8859 specifies a graphic symbol fo

44、r 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. AnnexB of ISO/IEC10367 gives further information on this subject. 5

45、.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 text

46、 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 character set This part of ISO/IEC8859 specifies191 charac

47、ters 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 subclause6.3.3. Control functions, such as BACKSPACE or CARRIAGE RETURN, shall not be used to create composite graphic sym

48、bols, which are made up from the graphic representations of two or more characters. 6.1 Characters of the set and their coded representation SeeTable 1.BSISO/IEC 8859-2:1999 4 BSI 02-2000 Table 1 Character set, coded representation Bit combination Hex Identifier Name 02/00 20 U+0020 SPACE 02/01 21 U
