ASCII

Area covered
7-bit coded character set for information interchange

Sponsoring body and standard details
American National Standards Institute (ANSI)

Characteristics/description
Specifies coding of SPACE and a set of 94 characters (letters, digits and punctuation or mathematical symbols) suitable for the interchange of English language documents. Forms the basis for most computer code sets and is the American National Version of ISO/IEC 646.

Usage (Market segment and penetration)
Used as the basic US code set for personal and workstation computers.

Further details available from:
ANSI, 11 West 42nd Street, New York, NY 10036, USA

A list of ASCII codes can be obtained via FTP from ftp://dkuug.dk/i18n/charmaps.all/ANSI_X3.4-1968.

EBCDIC

Area covered
8-bit coded character set for information interchange between IBM computers

Sponsoring body and standard details
Proprietary standard developed by IBM

Characteristics/description
A set of 57 national character sets for interchange of documents between IBM mainframes. Most EBCDIC character sets do not contain all of the characters defined in the ASCII code set but there is a special International Reference Version (IRV) code set that contains all of the characters in ISO/IEC 646 (and, therefore, ASCII).

Usage (Market segment and penetration)
Not much used outside of IBM and similar mainframe environments. When transmitting EBCDIC files between systems care needs to be taken to ensure that the systems are set up for the relevant national code set.

Warning: Unconverted EBCDIC documents can cause trouble if transmitted over the Internet as most of the alphanumeric codes have values greater than 128. (Some Internet nodes can strip the 8th bit off the code and transmit it as the 7-bit stem.)

ISO 646

Area covered
Unaccented Latin letters, digits and punctuation characters

Sponsoring body and standard details

• ISO/IEC JTC1/SC2 and ITU
• ISO/IEC 646:1991 Information technology -- ISO 7-bit coded character set for information interchange
• CCITT Recommendation T.50 (09/92) International Reference Alphabet (IRA)

Characteristics/description
Specifies 7-bit coding for SPACE and 94 characters. There is an International Reference Version (IRV), which is identical to ASCII, and national variants that provide accented and other special characters required in different countries.

Character positions 00-31 (ISO positions 0/0 to 1/15) and 127 (ISO position 7/15) are reserved for control codes. Code 32 (2/0) identifies a space. The sequence in which other codes appear in the IRV is:

! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @  A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ] ^ _ `  a b c d e f g h i j k l m n o p q r s t u v w x y z { | } ~   

Usage (Market segment and penetration)
Base character set used by most systems. Contains all characters provided by the standard shift positions of QWERTY keyboards.

ISO 2022

Area covered
Structure of 7-bit or 8-bit codetables, rules for code extension.

Sponsoring body and standard details

• ISO/IEC JTC1/SC2
• ISO/IEC 2022:1994 Information technology -- Character code structure and extension techniques

Characteristics/description
ISO standard for switching between code sets in 7-bit and 8-bit environments. Describes the role of the Escape, Shift-Out (SO) and Shift-In (SI) codes in the base control code set for controlling which character sets are used in an 7-bit environment, and how the role of these characters changes in an 8-bit environment to provide a locking shift code swapping function.

Up to 4 code sets (G0-G3) can be mapped into the left-hand side of an 8-bit ISO code set. Three of these (G1-G3) can also be used on the right-hand side. Escape code sequences are used to identify which code sets are to be used. Users can also select variant control code sequences using Escape code sequences. Escape code sequences are also used to provide a single character change of character sets.

Usage (Market segment and penetration)
Forms the basis for code switching in other standards, including SGML, but Shift functions are not used on standard hardware platforms, making use of this standard problematical.

ISO 6937

Area covered
Defines characters required for western European languages

Sponsoring body and standard details

• ISO/IEC JTC1/SC2 and ITU
• ISO/IEC 6937:1994 Information technology -- Coded graphic character set for text communication -- Latin alphabet
• ITU-T Recommendation T.51 (08/95) Latin-based coded character sets for telematic services

Characteristics/description
The left-hand side of this 8-bit code set is the based on ISO 646. The code set for the right-hand set of 94 characters contains a set of diacritical marks that can be combined with letters to produce accented characters, together with other characters used in European languages based on the Latin script that are not suitable for splitting into letter plus diacritic, such as the thorn (þ) used in Icelandic. The set also includes a set of single, double and French style angle open and closing quotation marks, Copyright and Registered symbols, the Spanish inverted question mark, some maths signs, fractions, superior numbers (2 and 3 only) and a set of arrows.

Usage (Market segment and penetration)
Basic character set used on teletext, videotext and related systems. CEN/CENELEC ENV 41501 covers its use in videotext services while CEN/CENELEC ENV 41502 covers its use in teletext services. For computers this code set has been superseded by ISO 8859 and ISO 10646. CEN/CENELEC ENV 41503 covers the use of both ISO 6937 and ISO 8859 for the interchange of text and data between information processing systems.

ISO 6937 also provides the character set repetoire used for X.400 message handling systems and X.500 directory services.

ISO 8859

Area covered
Defines accented and non-Latin characters used in European languages

Sponsoring body and standard details

• ISO/IEC JTC1/SC2
• ISO 8859 Information processing -- 8-bit single-byte coded graphic character sets
  • Part 1: Latin alphabet No. 1
  • Part 2: Latin alphabet No. 2

  • Part 7: Latin/Greek alphabet
  • Part 8: Latin/Hebrew alphabet
  • Part 9: Latin alphabet No. 5
  • Part 10: Latin alphabet No. 6

Characteristics/description
Specifies coding for sets of accented characters that cover the needs of most European languages, including limited sets of Greek, Hebrew and Arabic characters and some Cyrillic characters. Part 1 covers Western European languages, Part 2 covers Eastern European (Slavic, Albanian, Hungarian and Romanian) languages, Part 3 covers Southern European languages (Maltese) and Esperanto, and Part 4 covers Northern European languages. Part 9 covers characters used for Turkish, replacing those in Part 1 for Icelandic, while Part 10 deals with the Icelandic, Nordic and Baltic character sets.

Usage (Market segment and penetration)
Used by a few systems as the underlying code set. ISO 8859-1 is commonly used as the basis of extended 8-bit code sets within the European Community. Mixing of code sets is not permitted so that there are problems when trying to move between environments using different parts of the standard (e.g. Greece where Part 7 is used and the Netherlands, where Part 9 is officially preferred).

ISO 9541

Area covered
Provides mechanism for the interchange of information related to the metrics and drawing of glyphs used to display characters

Sponsoring body and standard details

• ISO/IEC JTC1/SC18 WG8
• ISO 9541:1991 Information technology -- Font information interchange
  • Part 1: Architecture
  • Part 2: Interchange Format
  • Part 3: Glyph shape representation
• ISO 10036:1996 Information technology -- Font information interchange -- Procedure for registration of font-related object identifiers

Characteristics/description
While other standards describe the numeric codes to be assigned to "characters" within a computer, this standard defines how information about the representation of these characters on a screen or a printed sheet should be interchanged. A single coded character can have many different physical representations, depending on the type face (font) being used. Each such representation forms a unique "glyph".

Part 1 of the standard explains the general architecture of the font information interchange standard. Part 2 defines the metrics used to describe the weight, width, height, etc, of a glyph. Part 3 defines how the information needed to generate a glyph should be interchanged, and defines ASN.1 and SGML interchange formats for this information.

ISO 9541 has been defined so that metric information can be interchanged separately from the more commercially sensitive glyph generation information. The metrics defined in Part 2 are of relevance to composition and other software that needs to calculate the relative position of glyphs. Only when the characters are actually being displayed/printed does access need to be provided to the much bulkier glyph drawing information. ISO 9541 Type 1 fonts are compatible with Version 23.0 of the Postscript interpreter.

A register of glyph identifiers is maintained on behalf of the ISO by Association for Font Information Interchange (AFII). This register is based on ISO/IEC 10036.

Usage (Market segment and penetration)
Not widely adopted yet as a competitor to the proprietary Truetype and Bitstream font interchange formats. The need for a truly international standard in this field is only just being recognized. It is considered to be of particular importance to the Far East marketplace.

• ISO/IEC DIS 14755 Information technology -- Input methods to enter characters from the repetoire of ISO/IEC 10646 with a keyboard or other input devices

Characteristics/description
Integrates all previous internationally/nationally agreed character sets into a single code set. ISO/IEC 10646 is based on 4 octet (32-bit) coding scheme known as the "canonical form" (UCS-4), but a 2-octet (16-bit) form (UCS-2) is used for the Basic Multilingual Plane (BMP), where octets 1 and 2 are assumed to be 00 00.

The code set is split into 128 "groups" of "planes" containing 256 "rows" with 256 "cells" for characters. Each character is addressed using multiple octets, the third (first) of which identifies the row containing the character and the fourth (second) its cell number.

The first 127 characters of the Basic Multilingual Plane (BMP) used for 16-bit code interchange are those of the ISO 646 International Reference Version of ASCII. The characters forming the second half of the first row are those used in ISO/IEC 8859-1, the Latin-1 character set. Other rows provide access to:

• eastern European accented characters
• the International Phonetic Alphabet (IPA)
• Greek (including accented characters, "monotoniko" and "polytoniko")
• Cyrillic, Georgian and Armenian
• Hebrew
• all four forms of Arabic characters (initial, medial, final and stand-alone)
• languages used on the Indian subcontinent (including Devanagari, Bengali, Gurmukhi, Gujarati, Oriya, Tamil, Telugu, Kannada and Malayalam)
• Thai and Lao
• Chinese/Japanese/Korean (CJK) ideographic characters (including Hangul, Katakana, Hiragana and Bopomofo)
• mathematical operators and special character forms
• box and line drawing characters
• geometric shapes and Dingbats
• special OCR characters used on cheques
• encircled characters and numbers.

Usage (Market segment and penetration)
Expected to become the basic coding form for all 16 and 32-bit computer systems during 1997.
