3、he agreed international 7-bit code for information interchange had led tothe development of many national, international and application-oriented versions of this code.These versions had a number of limitations generally inherent to the size of the code: they did not provide all graphic characters w
4、hich were needed; for some characters, specially for accented letters, it was necessary to resort to BACKSPACE sequences, whichcreated problems when processing data containing such composite characters; interchange among different versions was practically limited to the 82 common graphic characters.
5、With the advent of 8-bit coding it was possible to increase the number of graphic characters. ISO/IEC 6937, forexample, provided a character set covering the requirements of most languages based on the Latin alphabet. Thischaracter set, although well suited for text communication, was difficult to u
6、se for processing as some graphiccharacters were represented by one and others by two bit combinations.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 permitting easy
7、processing, takes into account character sets used in the industry.In 1982 the urgency of the need for an 8-bit single-byte coded character set was recognized in ECMA as well as inANSI/X3L2 and numerous working papers were exchanged between the two groups. In February 1984 ECMA TC1submitted to ISO/T
8、C97/SC2 a proposal for such a coded character set. At its meeting of April 1984 SC2 decided tosubmit to TC97 a proposal for a new item of work for this topic. Technical discussions during and after this meetingled TC1 to adopt the coding scheme proposed by X3L2. International Standard ISO/IEC 8859-1
9、 is based on this jointANSI/ECMA proposal. ECMA published 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 followingresults:i. A first Edition, dated June 1986, of a Standard for a Latin/Cyrilli
10、c coded graphic character set.ii. The second Edition of Standard ECMA-94, dated June 1986, comprising four coded graphic character sets forthe Latin script, identified as Latin Alphabets No. 1 to No. 4. These alphabets have a number of characters incommon, in particular those allocated to columns 02
11、 to 07. They have all been submitted to ISO/IEC JTC 1 - thesuccessor of ISO/TC97 - and are the subject of ISO/IEC 8859, Parts 1 to 4.iii. A series of ECMA Standards for coded graphic character sets comprising those characters of the Latin Alphabetsallocated to columns 02 to 07 and characters of anot
12、her script for multiple-language applications. TheseStandards ECMA-114, ECMA-118 and ECMA-121 cover the Arabic, Greek and Hebrew scripts, respectively.They have been submitted to JTC 1 for further processing as ISO/IEC standards and have been published as Part6, Part 7 and Part 8, respectively, of I
13、SO/IEC 8859.The 2ndEdition of Standard ECMA-113 superseded the first edition. Indeed, the latter was based on the 1974 versionof GOST Standard 19768. In 1987 this standard was revised. As a consequence the 2ndEdition was prepared in co-operation with Russian experts and was brought in complete agree
14、ment with the corresponding GOST standard. Thecorresponding International Standard, ISO/IEC 8859-5:1988 is technically identical with the 2ndEdition ofECMA-113.In 1999 the 2ndEdition of ISO/IEC 8859-5 has been published, as a technical revision of the 1stEdition of thisInternational Standard. The 3r
15、dEdition of ECMA-113 has been made technically identical with the 2ndEdition ofISO/IEC 8859-5.This 3rdEdition of Standard ECMA-113 has been adopted by the ECMA General Assembly of December 1999.- i -Table of contents1Scope 12 Conformance 12.1 Conformance of information interchange 12.2 Conformance o

20、se in data and text processing applications and also forinformation interchange. The set contains graphic characters used for general purpose applications in typicaloffice environments in at least the following languages:Bulgarian, Byelorussian, English, Latin, (Slavic) Macedonian, Russian, Serbian
21、and Ukrainian.NOTETwo letters recently added to the Ukrainian official alphabet are not included in the character set of thisStandard. For a background the CEN/CENELEC/PT004 Report may be consulted (see annex C).This set of coded graphic characters may be regarded as a version of an 8-bit code accor

If coded characters from more that one ECMA Standard are to be used together, by means of codeextension techniques, the equivalent cod
23、ed character sets from ISO/IEC 10367 should be used instead withina version of Standard ECMA-43 at level 2 or level 3.The coded characters in this ECMA Standard may be used in conjunction with coded control functionsselected from ECMA-48. However, control functions are not used to create composite g
