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
nongovernmental, 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 JTC1. 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.
International Standard ISO/IEC 8859-8 was prepared by Joint
Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 2, Coded character sets.
This edition cancels and replaces ISO 8859-8:1988 which has been
technically revised.
ISO/IEC 8859 consists of the following parts, under the general title
Information technology – 8-bit single-byte coded graphic character
sets:
– Part 1: Latin alphabet No. 1
– Part 2: Latin alphabet No. 2
– Part 3: Latin alphabet No. 3
– Part 4: Latin alphabet No. 4
– Part 5: Latin/Cyrillic alphabet
– Part 6: Latin/Arabic alphabet
– Part 7: Latin/Greek alphabet

Introduction
ISO/IEC 8859 consists of several parts. Each part specifies a set of
up to 191 graphic characters and the coded representation of these
characters by means of a single 8-bit byte. Each set is intended for
use for a particular group of languages.
