2、nternational 7-bit code for information interchange had led to the development of many national, international and application-oriented versions of this code which are in wide use today. These versions have a number of limitations generally inherent to the size of the code: - they do not provide all

3、 graphic characters which may be needed, - for some characters, 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 different versions is practically limited to the 8

4、2 common graphic characters. With the advent of 8-bit coding 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

5、communication, is difficult to use for processing as some graphic 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 gr

6、aphic characters thus permit- - takes into account character 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

7、 ECMA TC1 submitted to ISO/TC97/SC2 a proposal for such a coded 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. Interna

8、tional Standard IS0 8859/1 is based on this joint ANSI/ECMA proposal. ECMA published the 1st edition of its corresponding Standard ECMA-94 in March 1985. After this first publication, the work of ECMA TC1 on further coded graphic character sets has led to the following results: ting easy processing,

It will be submitted to IS0 for processing under the fast-track procedure. ECMA ECMA*LLB 86 3404593 OOOLL94 L E ii) The second Edition of Standard ECMA-9

These alphabets have a number of characters in common, in particular those al- located to columns 02 to 07. Latin Alphabet No 2 has been sub- mitted to IS0 and is the

11、subject of IS0 8859/2. Latin Alphabets No. 3 and No. 4 are processed as IS0 DP 8859/3 and DP 8859/4. iii) A series of ECMA Standards for coded graphic character sets comprising those characters of the Latin Alphabets allocated to columns 02 to 07 and characters of another script for multi- ple-langu

12、age applications. These ECMA standards cover the Cyrillic and Arabic scripts. They have been submitted to IS0 as DIS 8859/5 and DIS 8859/6, respectively, for fast-track pro- cessing as IS0 standards.

SCOPE This ECMA Standard defines a set of 185 graphic characters iden- tified as Latin/Greek Alphabet, and specifies the coded repre- sentation of each of these characters by means of a single 8-bit

16、byte. None of these characters are lvnon-spacing“. The use of control functions, such as BACKSPACE or CARRIAGE RETURN for the coded representation of composite characters is prohibited by this Standard. 2. FIELD OF APPLICATION This set of graphic characters, the Latin/Greek Alphabet, is in- tended f

It allows handling of data and text expressed in Greek. This set of graphic characters is suitable for us

18、e in a version of an 8-bit code according to ECMA-35 or ECMA-43. 3. CONFORMANCE A set of graphic characters is in conformance with this Standard if it comprises all graphic characters specified herein to the exclusion of any other and if their coded representations are those specified by this Standa

DEFINITIONS For the purpose of this Standard the following definitions apply: 5.1 Bit Combination; Byte An ordered set of bits that represents a character

21、 or is used as a part of the representation of a character. _ ECMA ECMA*LLB Bb 3404593 OOOLL97 7 I 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, con- trol or representation of data. Coded Character Set; Code A set of unambiguous rules that establishes

22、 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 a code. Graphic Character A character, other than a control function, that has a visual representation norm

23、ally 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 each character. Graphic Symbol A visual representation of a graphic character. Position That part of a code ta

24、ble 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 b, b, b6, b5, b, b, b, and b, where b, is the high- est-order, or most-significant bit and b, is the lowest-order, or least-signifi

25、cant bit. The bit Combinations may be interpreted to represent numbers in binary notation by attributing the following weights to the individual bits: Bit bl3 b7 b6 b5 b4 b3 bz bi Weight 128 64 32 16 8 4 2 1 . Using these weights, the bit combinations of the 8-bit code represent numbers in the range

26、 .O to 255. In this Standard, the bit combinations are identified by nota- tions of the form xx/yy, where xx and n are numbers in the range O0 to 15. The correspondence between the notations of the form xx/yy and the bit combinations consisting of the bits b, to b, is as fOllOWS: ECMA ECMA*KLKLB ib

27、a 3404593 0001L98 9 m -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 respectively; bits are given the weights 8, 4, 4 and 1 respectively. 6.2 Layout of the Code Table An 8-bit c

28、ode table consists of 256 positions arranged in 16 columns and 16 rows. The columns and the rows are numbered O0 to 15. 6.3 The code tible positions are identified by notations of the form xx/yy, where xx is the column number and yy is the row number. The positions of the code table are in one-to-on

29、e 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. Names and Meaninqs This Standard assigns at least one name to each character. In addition, it specifies a graphic symbol for e

30、ach graphic char- acter. 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 intended to reflect their customary meaning. However, except for SPACE (SP), NO-BREAK SPAC

31、E (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. 6.3.1 SPACE (SP) This character may be interpreted as a graphic character, a control cha

32、racter 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 the absence of a graphic symbol, for use when a line break is to be prevented in the text as presented. 6.3.2

33、 NO-BREAK?SPACE (NBSP) 6.3.3 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. -4- 7.
