8-Bit Character Sets - ISO 2375 Register
- ISO 2375 Register
- International Register of Coded Character Sets to be used with Escape
This register is updated as additional entries are approved in accordance with the procedures of ISO 2375. It does not have
discrete editions. It is available from the Registration Authority:
IPSJ/ITSCJ (Information Processing Society of Japan/Information Technology Standards Commission of Japan)
Room 308-3, Kikai-Shinko-Kaikan Bldg., 3-5-8, Shiba-Koen, Minato-ku, Tokyo 105 JAPAN
The register used to be available free of charge in paper form. However, the register is now available in a much more convenient form electronically on the Web.
This register contains the specifications of all coded character sets and
control functions that can be brought into use by means of escape sequences.
Many, but not all, of the coded character sets specified in the register are
taken from national and international standards.
Each register entry is assigned a registration number that provides an
unambiguous method for referencing that entry. It is specified in ISO 2375
that the entry with registration number nn should be referenced as ISO-IR nn.
The ISO 2375 Register is divided into the following sections and
- Graphic character sets
- 94-character sets, i.e. 94-position single-byte sets
- 96-character sets, i.e. 96-position single-byte sets
- Multiple-byte sets, which may be either 94-position or 96-position sets
- Control character sets
- C0 sets of control characters
- C1 sets of control characters
- Single control functions
- Coding systems different from that of ISO/IEC 2022
- Coding systems with a standard return
- Coding systems without a standard return
The registration numbers and escape sequences for a number of register entries are given elsewhere in this guide. These entries may be found as follows:
- For 94-character single-byte sets that provide national and other versions of ISO/IEC 646 (variants of ASCII), see ISO/IEC 646.
- For 96-character single-byte sets that supplement ISO-IR 6 (ASCII) to
provide characters of the Greek, Cyrillic, Arabic and Hebrew scripts and
additional Latin characters, see ISO/IEC 10367.
This reference includes the character sets of ISO/IEC
6937 and ISO/IEC 8859.
- For two-byte sets from Chinese, Japanese and Korean national standards
that provide coding for ideographic scripts, see the section on ideographic scripts for Chinese, Japanese and Korean.
- For single control functions for code extension, see the section on locking shifts.
Register entries which specify C0 and C1 sets of control functions include:
The escape sequences listed designate these sets as the C0 or C1 code element,
- C0 sets:
- ISO-IR 1 (ESC 02/01 04/00) : C0 set of ISO/IEC
- ISO-IR 104 (ESC 02/01 04/07) : Minimum C0 set for ISO/IEC 4873
This set comprises only the character ESCAPE (ESC).
- ISO-IR 106 (ESC 02/01 04/05) : Teletex primary set of Control Functions
of CCITT Recommendation T.61.
This set comprises the control characters BACKSPACE (BS), LINE FEED (LF), FORM
FEED (FF), CARRIAGE RETURN (CR), LOCKING SHIFT ZERO (LS0), LOCKING SHIFT ONE
(LS1), SINGLE-SHIFT TWO (SS2), SINGLE-SHIFT THREE (SS3), SUBSTITUTE CHARACTER
(SUB) and ESCAPE (ESC) only.
- C1 sets:
- ISO-IR 77 (ESC 02/02 04/03) : C1 set of ISO
The C1 set of ISO/IEC 6429:1992 is designated as the first revision of ISO-IR
77 by means of the escape sequences ESC 02/06 04/00 ESC 02/02 04/03; see designation of sets of control functions in the
section of this guide on control functions.
- ISO-IR 105 (ESC 02/02 04/07): Minimum C1 set for ISO/IEC 4873
This set comprises only the control characters SINGLE-SHIFT TWO (SS2) and
SINGLE-SHIFT THREE (SS3).
- ISO-IR 107 (ESC 02/02 04/08) : Teletex supplementary set of Control
Functions of CCITT Recommendation T.61.
This set comprises the control functions PARTIAL LINE UP (PLU), PARTIAL LINE
DOWN (PLD) and CONTROL SEQUENCE INTRODUCER (CSI) only.
