1、ECMA EUROPEAN COMPUTER MAN U FACTURER S ASSOCIATION STANDARD ECM1A-94 8-BIT SINGLE-BYTE CODED GRAPHIC CHARACTER SETS LATIN ALPHABETS No. 1 TO No. 4 2nd Edition - June 1986 - f BRIEF HISTORY The adoption of ECMA-6 (IS0 646) as the agreed international 7-bit code for information interchange had led to

2、 the development of many national, international and application-oriented versions of this code which are in wide used today. These versions have a number of limitations generally inherent to the size of the code: - they do not provide all graphic Characters which may be needed, - for some character

3、s, specially for accented letters, it is neces- sary to resort to BACKSPACE sequences, which creates problems when processing data containing such composite characters, - interchange among diEferent versions is practically limited to the 82 common graphic characters. With the advent of 8-bit coding

4、it was possible to increase the num- ber of graphic characters. IS0 6937/2, for example, provides a char- acter set covering the requirements of most languages based on the Latin alphabet. This character set, although well suited for text communication, is difficult to use for processing as some gra

5、phic characters are represented by one and others by two bit combina- tions. Thus the need was recognized for coded graphic character sets, each of which: - is the same for all users of a given area, - provides single-byte coding of all graphic characters thus permit- - takes into account character

6、sets used in the industry. Since 1982 the urgency of the need for an 8-bit single-byte coded character set was recognized in ECMA as well as in ANSI/X3L2 and nu- merous working papers were exchanged between the two groups. In February 1984 ECMA TC1 submitted to ISO/TC97/SC2 a proposal for such a cod

7、ed character set. At its meeting of April 1984 SC2 decided to submit to TC97 a proposal for a new item of work for this topic. Technical discussions during and after this meeting led TC1 to adopt the coding scheme proposed by X3L2. International Standard IS0 8859/1 is based on this joint ANSI/ECMA p

8、roposal. ECMA published its corresponding Standard ECMA-94 in March 1985. ting easy processing, After this first publication, the work of ECMA TC1 on further coded graphic character sets has led to the following results: i) The present second Edition of Standard ECMA-94 comprising four coded graphic

9、 character sets for the Latin script, identified as Latin Alphabets No 1 to No 4. These alphabets have a number of characters in common, in particular those allocated to columns 02 to 07. Latin Alphabet No 2 has been submitted to IS0 and is the subject of IS0 8859/2. ECMA ECMAU94 8b m 3404593 000726

These ECMA standards cover the Cyril- lic, Greek and Arabic scripts. It is

SCOPE This ECMA Standard defines four 8-bit coded graphic character sets identified as Latin Alphabets No 1 to No 4, and specifies the coded

17、representation of each character by means of a single 8-bit byte. Characters common to two or more sets are allocated to the same code position. None of these characters are %on-spacingl. The use of control functions, such as BACKSPACE or CARRIAGE RETURN for the coded representation of composite cha

18、racters is prohibited by this Standard. 2. FIELD OF APPLICATION These sets of graphic characters are intended for use in data and text processing applications and may also be used for infor- mation interchange. They are suitable for use in a version of an 8-bit code according to ECMA-35 or ECMA-43.

19、A specific field of application is indicated for each character set. 3. CONFORMANCE A set of graphic characters is in conformance with this Standard if it comprises all graphic characters specified for one of the Latin Alphabets to the exclusion of any other and and if their coded representations ar

20、e those specified by this Standard. Any claim of conformance shall specify the Latin Alphabet imple- mented. 4.

DEFINITIONS For the purpose of this Standard t

22、he following definitions apply: 5.1 Bit Combinations; Byte An ordered set of bits that represents a character or is used as a part of the representation of a character. ECMA ECMA*94 8b W 3404593 0007270 T-E 5.2 5.3 5.4 5.5 5.6 5.7 -2- Character A member of a set of elements used for the organization

23、, con- trol or representation of data. Coded Character Set; Code A set of unambiguous rules that establishes a character set and the one-to-one relationship between each character of the set and its coded representation. Code Table A table showing the character allocated to each bit combina- tion in

24、 a code. 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 1 In this Standard a single bit combination is used to represent ea

25、ch graphic character. Graphic Symbol A visual representation of a graphic character. Position That part of a code table identified by its column and row co-ordinates. 6. NOTATION, CODE TABLE AND NAMES 6.1 Notation The bits of the bit combinations of the 8-bit code are identi- fied by b8, b, b, b, b,

26、 bg, b2 and b, where b8 is the highest-order, or most-significant bit and b, is 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: I Weight1 128 64 32 16 8 4 Using th

27、ese weights, the bit combinations of the 8-bit code are interpreted to represent numbers in the range O to 255. In this Standard, the bit combinations are identified by nota- tions of the form xx/yy, where xx and yy are numbers in the range O0 to 15. The correspondence between the notations of the f

28、orm xx/yy and the bit combinations consisting of the bits b, to b, is as follows: .- y- ECMA ECMA*94 86 = 3404593 0007271 1 - - - -3- - xx is the number represented by b, b, b, and b, where these - yy is the number represented by b, b, b, and b, where these bits are given the weights 8, 4, 2 and 1 r

29、espectively; bits are given the weights 8, 4, 2 and 1 respectively. 6.2 Layout of the Code Tables Each 8-bit code table consists of 256 positions arranged in 16 columns and 16 rows. The columns and the rows are numbered O0 to 15. The code table positions are identified by notations of the form xx/yy

30、, where xx is the column number and YJT is the row number. The positions of the code table are in one-to-one correspon- dence with the bit combinations of the code. The notation of a code table position, of the form xx/yy, is the same as that of the corresponding bit combination, This Standard assig

31、ns at least one name to each character. In addition, it specifies a graphic symbol for each graphic character. By convention only capital letters, the graphic symbols of small letters and hyphens are used for writing the names of the characters. The names chosen to denote graphic characters are inte

32、nded to reflect their customary meaning. However, except for SPACE (SP), NO-BREAK SPACE (NBSP) and SOFT HYPHEN (SHY), this Stan- dard does not define and does not restrict the meanings of graphic characters. Neither does it specify a particular style or font design for imaging graphic characters. 6.

33、3 Names and Meaninqs 6.3.1 SPACE (SPI This character may be interpreted as a graphic character, a control character or as both. As a graphic character it has the visual representation consisting of the absence of a graphic symbol. A graphic character the visual representation of which con- sists of

34、the absence of a graphic symbol, for use when a line break is to be prevented in the text as presented. A graphic character that is imaged by a graphic symbol identical with, or similar to, that representing HYPHEN, for use when a line break is permitted in the text as presented. 6.3.2 NO-BREAK SPAC

SPECIFICATION OF THE FOUR LATIN ALPHABETS The four Latin Alphabets have 128 common characters, namely the 95 characters allocated to columns 02 to 07 and 33 characters allocated to code positions in columns 10 to 15. For th

36、e sake of simplicity the characters allocated to columns 02 to 07 are listed once only. The characters in columns 10 to 15 are listed for each Latin Al- phabet and the complete code table is shown for each of them. 7.1 Characters Allocated to Column 02 to 07 in each Latin Alphabet Bit Combination 02
