ISO/IEC 2375:2003

Information technology - Procedure for registration of escape sequences and coded character sets

ISO/IEC 2375:2003 specifies the procedures to be followed for preparing, maintaining, and publishing a register of escape sequences and of the coded character sets they identify. The registration process specified in ISO/IEC 2375:2003 is not a procedure for standardization of characters or coded character sets. Organizations that wish ISO and/or IEC to create an international standard for a coded character set or that wish ISO and/or IEC to code additional characters into ISO/IEC 10646 need to follow the ISO/IEC procedures for doing so. In particular, Registration of a coded character set according to the procedures specified by ISO/IEC 2375:2003 implies no commitment by ISO and/or IEC to adopt the coded character set as an ISO/IEC standard. The existence of a character in an approved registration does not imply a commitment by ISO and/or IEC to encode that character into ISO/IEC 10646. ISO/IEC 2022 describes the escape sequences referenced in ISO/IEC 2375:2003, except for escape sequences reserved in ISO/IEC 2022 for private use. The use of these escape sequences includes code extension, that is, the provision of additional sets of characters, or of additional control functions, in accordance with ISO/IEC 2022. An escape sequence registered in accordance with ISO/IEC 2375:2003 serves as an identification of the character, the set of characters, or the control function associated with it in the register. The registration itself does not specify the rules in accordance with which a character or character set identified by an escape sequence is to be used. Rather, the registration identifies the documents (for example, standards) which specify such rules.

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 2375 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 2, Coded character sets.
This first edition of ISO/IEC 2375 cancels and replaces ISO 2375:1985, which has been technically revised.

Introduction
International standard coded character sets have been adopted for the interchange of information between

information processing systems and within message transmission systems. However, circumstances occur where
applications require characters which are not included in a single international standard character code or which are
in a character code which is not an international standard.
Provision for additional characters is made by code extension techniques in which the additional coded character
sets are identified by escape sequences. The procedures for code extension and the structure and use of escape
sequences are fully documented in ISO/IEC 2022, which defines classes of escape sequences, but does not assign
specific meanings to individual escape sequences. Instead, it depends on this standard, ISO/IEC 2375, and the
associated International Registry, to assign the meanings.
This International Standard specifies the procedures to be followed in preparing and maintaining a register of
specific escape-sequence meanings. The register associates escape sequences with specific coded character sets.
The purpose of this register is to inform interested parties about coded character sets already developed and of the
specific escape sequences assigned to them.
The publication of the register should promote compatibility in international information interchange and avoid
duplication of effort in developing application-oriented coded character sets. Registration provides a standardized
identifier for a coded character set, but it is not a procedure to standardize a coded character set. Nevertheless, as
a matter apart from registration the coded character set may, but need not, be the subject of an international,
national, or other standard. When such a standard is prepared after the registration of an escape sequence, it would
be appropriate to specify the escape sequence which identifies the coded character set in the standard itself.
