ISO 8859-7:1987

Information processing — 8-bit single-byte coded graphic character sets — Part 7: Latin/Greek alphabet

This part of ISO 8859 defines a set of 185 graphic characters identified as the Latin/Greek alphabet, and specifies the coded representation of each of these characters by means of a single 8-bit byte. None of these characters are "non-spacing". The use of control functions, such as BACKSPACE or CARRIAGE RETURN for the coded representation of com­posite characters is prohibited by ISO 8859.

Traitement de l'information — Jeux de caractères graphiques codés sur un octet — Partie 7: Alphabet latin/grec

La présente partie de l'ISO 8859 définit un jeu de 185 caractères graphiques, portant le nom d'alphabet latin/grec, et la représentation codée de chacun de ces caractères sur un seul octet. Aucun de ces caractères n'est «sans espacement». L'utilisation de fonctions de contrôle telles que ESPACE ARRIÈRE ou RETOUR CHARIOT pour la représentation codée de caractères composés est interdite par l'ISO 8859. Ce jeu de caractères graphiques, l'alphabet latin/grec, est destiné aux applications de traitement de texte et de données et peut également servir à l'échange d'informations. Il est destiné aux applications multilingues comportant des écritures latines et grecques. Il permet le traitement de données et de textes écrits en grec. Ce jeu de caractères graphiques peut être utilisé dans une version d'un code à 8 éléments conforme à l'ISO 2022 ou à l'ISO 4873. NOTE -- L'ISO 8859 n'est pas destinée à être utilisée pour les services télématiques définis par le CCITT. Si des informations codées conformément à l'ISO 8859 doivent être transférées à de tels services, elles devront se conformer aux spécifications de ces services au niveau de l'interface de codage.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 8859-7 was prepared by the European Computer Manufac-
turers Association as standard ECMA-118 and was adopted, under a special “fast-
track” procedure, by Technical Committee ISO/TC 97, information processing
systems, in parallel with its approval by the IS0 member bodies.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
