ISO/IEC 8859-11:2001

Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet

This part of ISO/IEC 8859 specifies a set of 183 coded graphic characters identified as Latin/Thai alphabet. This set of coded graphic characters is intended for use in data and text processing applications and also for information interchange. The set contains graphic characters used for general purpose applications in typical office environments in at least the following languages: Thai, English and Latin. Some of the characters in this set are combining characters (see clause 6). This set of coded graphic characters may be regarded as a version of an 8-bit code according to ISO/IEC 2022 or ISO/IEC 4873 at level 1. This part of ISO/IEC 8859 may not be used in conjunction with any other parts of ISO/IEC 8859. If coded characters from more than one part are to be used together, by means of code extension techniques, the equivalent coded character sets from ISO/IEC 10367 or their corresponding G1 sets from ?ISO International Register of Coded Character Sets to be used with escape sequences', should be used instead within a version of ISO/IEC 4873 at level 2 or level 3. The coded characters in this set may be used in conjunction with coded control functions selected from ISO/IEC 6429. However, control functions are not used to create composite graphic symbols from two or more graphic characters (see clause 6). NOTE ? ISO/IEC 8859 is not intended for use with Telematic services defined by ITU-T. If information coded according to ISO/IEC 8859 is to be transferred to such services, it will have to conform to the requirements of those services at the access-point.

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 3.
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
part of ISO/IEC 8859 may be the subject of patent rights. ISO and IEC
shall not be held responsible for identifying any or all such patent
rights.
