rJisplous news Graphic character coding standards The European Computer Manu- facturers Association (ECMA) Technical Committee 1 has con- tmued its development work on 8 bit single byte coded graphic character sets. The first edition of Standard ECMA-94 was issued m March 1985, its contents having become international standard ISO 8859/1. The second edition of ECMA-94 comprises the four Latin alphabets Nos 1-4. Latin alphabet No 2 is also the subject of an inter- national standard, ISO 8859/2.

Graphic character coding standards The European Computer Manu- facturers Association (ECMA) Technical Committee 1 has con- tmued its development work on 8 bit single byte coded graphic character sets. The first edition of Standard ECMA-94 was issued m March 1985, its contents having become international standard ISO 8859/1. The second edition of ECMA-94 comprises the four Latin alphabets Nos 1-4. Latin alphabet No 2 is also the subject of an inter- national standard, ISO 8859/2. Latin alphabets Nos 3 and 4 are p rocessed m ISO as draft propo- sals for an international standard DP 8859/3 and DP 8859/4, respec- tively.

Each of these alphabets speci- fies an 8 bit single byte coded graphic character set which covers the requirements and needs for geographical areas comprising different languages. For instance, Latin alphabet No 1
