European character repertoires and their coding - 8-bit single-byte coding

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).

Informationstechnik - Europäische Zeichenvorräte und deren Codierung - 8-Bit-Einzelbyte-Codierung

Diese Technische Spezifikation legt die Schriftzeichenvorräte sowie deren Einzelbyte-Codierungen der Sprachen fest, die von den CEN/CENELEC-Mitgliedern und den Institutionen der Europäischen Union und der Europäischen Freihandelszone bevorzugt verwendet werden und die für den Informationsaustausch zwischen Informationsverarbeitungssystemen und für die Anwendung innerhalb dieser Systeme zur Verfügung stehen.
Diese Technische Spezifikation trifft keine Festlegungen hinsichtlich des Austausches von Informationen in oder mit Telematikdiensten. Der in einem solchen Dienst verwendete Zeichenvorrat und dessen Codierung sind in den Spezifikationen des Telematikdienstes festgelegt. Werden dieser Technischen Spezifikation entsprechende Informationen mit Hilfe eines Telematikdienstes übermittelt, kann es nötig werden, die Anzahl der Zeichen in einem Zeichenvorrat anzupassen (Zeichenvorrats-Umsetzungsfunktion) oder die Codierung zu ändern (Code-Umsetzungsfunktion).

This Technical Specification (CEN/TS) was approved by CEN on 16 October 2002 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their

comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available. It

is permissible to keep conflicting national standards in force (in parallel to the CEN/TS) until the final decision about the possible

conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,

Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United

Kingdom.

Foreword

This document (CEN/TS 1923:2003) has been prepared by Technical Committee CEN/TC 304, "Information and

communications technology - European localization requirements", the secretariat of which is held by SIS.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun-

tries are bound to announce this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France,

Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia,

Spain, Sweden, Switzerland and the United Kingdom.

This Technical Specification is a revision of the European Standard EN 1923:1998, which it cancels and replaces.

The main purpose of the revision is to include, and thereby to publicize the availability of, 8-bit code tables devel-

oped after the publication of EN 1923:1998; in particular the code table of ISO/IEC 8859-15 and the tables of other

additions to the ISO/IEC 8859 series. Although CEN/TC 304 decided that a revision of the contents of EN

1923:1998 was necessary, some uncertainty existed whether the standard as such is needed by the data commu-

nity in the present-day direction towards multi-octet coding schemes. The committee therefore decided to classify

the revised document as a Technical Specification. Its usefulness will thereby become evaluated.

The contents of this document differs from that of EN 1923:1998 in the following respects:

– Extensive editorial changes have been made to the text for conformance with present CEN/CENELEC drafting

rules.

– Additional coding scheme options have been introduced, corresponding to ISO/IEC 8859 parts 14, 15 and 16

(Latin-8, Latin-9 and Latin-10), and also to ISO-IR 204 ("Latin-1 alternative with Euro").

– For consistency, the definitions of all options now refer to registrations according to ISO 2375:1985 in the ISO

"International register of coded character sets to be used with escape sequences". Relationships to ISO/IEC

10646-1:2000 specifications are also given, to the extent applicable.

– An informative Annex A has been added, containing ISO/IEC 10646-1:2000 identifications for all characters in

the options character sets.

– An informative Annex B has been added, listing relationships to ISO/IEC 7/8-bit coding standards.

– An informative Annex C has been added, illustrating the code tables for all options.
