Information technology -- Universal Multiple-Octet Coded Character Set (UCS)
ISO/IEC 10646:2003 specifies the Universal Multiple-Octet Coded Character Set (UCS). It is applicable to the representation, transmission, interchange, processing, storage, input and presentation of the written form of the languages of the world as well as additional symbols.
ISO/IEC 10646:2003
specifies the architecture of ISO/IEC 10646:2003;
defines terms used in ISO/IEC 10646:2003;
describes the general structure of the coded character set;
specifies the Basic Multilingual Plane (BMP) of the UCS;
specifies supplementary planes of the UCS: the Supplementary Multilingual Plane (SMP), the Supplementary Ideographic Plane (SIP) and the Supplementary Special-purpose Plane (SSP);
defines a set of graphic characters used in scripts and the written form of languages on a world-wide scale;
specifies the names for the graphic characters of the BMP, SMP, SIP, SSP and their coded representations;
specifies the four-octet (32-bit) canonical form of the UCS: UCS-4;
specifies a two-octet (16-bit) BMP form of the UCS: UCS-2;
specifies a multiple byte (one to four) byte transformation UTF-8 for use with ISO 646 (ASCII) byte-oriented environments;
specifies a two 16-bit form and associated transformation UTF-16 for supplementary characters;
specifies collection identifiers for selected set of character subsets;
specifies the coded representations for control functions;
specifies the management of future additions to this coded character set;
incorporates the Unicode bi-directional algorithm and normalization forms by reference.
The UCS is a coding system different from that specified in ISO/IEC 2022. A graphic character will be assigned only one code position in ISO/IEC 10646:2003, located either in the BMP or in one of the supplementary planes.
NOTE - The Unicode Standard, Version 4.0 includes a set of characters, names, and coded representations that are identical with those in ISO/IEC 10646:2003. It additionally provides details of character properties, processing algorithms, and definitions that are useful to implementers. Version 4.0 strengthens Unicode support for worldwide communication, software availability, and publishing.
By defining a consistent way of encoding multilingual text ISO/IEC 10646:2003 enables the exchange of data internationally. The information technology industry gains data stability, greater global interoperability and data interchange. ISO/IEC 10646:2003 has been widely adopted in new Internet and W3C protocols and mark up languages such as XML and HTML, and implemented in modern operating systems and computer programming languages. This edition covers over 96 000 characters from the world's scripts.
Technologies de l'information -- Jeu universel de caractères codés sur plusieurs octets (JUC)
L'ISO/CEI 10646:2003 normalise le jeu universel de caractères codés sur plusieurs octets (JUC). Elle s'applique à la représentation, à la transmission, à l'échange, au traitement, au stockage, à la saisie et à la présentation des langues du monde sous forme écrite et de symboles complémentaires.
L'ISO/CEI 10646:2003
décrit l'architecture de l'ISO/CEI 10646:2003,
définit les termes utilisés dans l'ISO/CEI 10646:2003,
décrit la structure générale du jeu de caractères codés,
décrit le plan multilingue de base (PMB) du JUC,
décrit les plans complémentaires du JUC: le Plan multilingue complémentaire (PMC), le Plan idéographique complémentaire (PIC) et le Plan complémentaire spécialisé (PCS),
définit un ensemble de caractères graphiques utilisés dans la forme écrite des langues à l'échelle mondiale,
nomme et établit la représentation codée des caractères graphiques du PMB, du PMC, du PIC et du PCS,
prescrit la forme canonique à quatre octets (32 bits) du JUC: UCS-4,
précise une forme du PMB à deux octets (16 bits) pour le JUC: UCS-2,
établit la représentation codée des fonctions de commandes, et
établit la gestion de tout développement ultérieur du présent jeu de caractères codés.
Le JUC est un système de codage différent de celui décrit dans l'ISO/CEI 2022. Un caractère graphique donné ne sera affecté qu'à une seule position de code dans l'ISO/CEI 10646:2003, située soit dans le PMB, soit dans un des plans complémentaires.
NOTE - La version 4.0 d'Unicode définit un ensemble de caractères, de noms et de représentations codées identiques à l'ensemble de l'ISO/CEI 10646:2003. Elle fournit, de surcroît, des informations supplémentaires relatives aux propriétés de ces caractères, aux algorithmes de traitement ainsi que des définitions utiles aux développeurs.
En définissant une manière cohérente de coder du texte multilingue, l'ISO/CEI 10646:2003 permet l'échange de données au niveau international. L'industrie des technologies de l'information y gagne en stabilité des données et en une meilleure interopérabilité mondiale. L'ISO/CEI 10646:2003 a été adoptée par de nouveaux protocoles Internet et mise en oeuvre dans des systèmes d'exploitation et des langages informatiques. Cette édition contient plus de 95 000 caractères des écritures du monde entier.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 10646 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 2, Coded character sets.
This first edition of ISO/IEC 10646 cancels and replaces ISO/IEC 10646-1:2000 and ISO/IEC 10646-2:2001. It
also incorporates ISO/IEC 10646-1:2000/Amd.1:2002.
