This Technical Specificationspecifies the graphic char-ac-ter repertoires and their single-byte coding, which are available for use for information inter-change between information processing systems and for use within such systems, in the scripts that are commonly used by the members of CEN/CENELEC and the Institutions of the European Union and the European Free Trade Association. This Technical Specificationdoes not specify the interchange of information using a telematic service. The character repertoire and the coding used by a telematic service are defined by the specification of that service. The transmission of information based on the specifications of this Technical Specificationusing a telematic service may necessitate an adaptation of the number of characters of a repertoire (repertoire transformation function) or a change to the coding (code transformation function).
