'''ISO/IEC&nbsp;646''' is a set of [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]] standards, described as ''Information technology&nbsp;—&nbsp;ISO&nbsp;7-bit coded character set for information interchange'', and developed in cooperation with [[ASCII]] at least since 1964.<ref name="Ptak_2012"/><ref name="ISO_1964"/> Since its first edition in 1967<ref name="Mackenzie_1980"/> it has specified a 7-[[bit]] character code from which several national standards are derived.

ISO/IEC 646 was also ratified by [[Ecma International|ECMA]] as '''ECMA-6'''. The first version of ECMA-6 had been published in 1965,<ref name="ECMA-6_1985"/> based on work the ECMA's Technical Committee TC1 had carried out since December 1960.<ref name="ECMA-6_1985"/>

Characters in the ISO/IEC&nbsp;646 Basic Character Set are ''invariant characters''.<ref name="Bodfish_2013"/> Since that portion of ISO/IEC&nbsp;646, that is the ''invariant character set'' shared by all countries, specified only those letters used in the [[ISO basic Latin alphabet]], countries using additional letters needed to create national variants of ISO/IEC&nbsp;646 to be able to use their native scripts. Since transmission and storage of 8-bit codes was not standard at the time, the national characters had to be made to fit within the constraints of 7 bits, meaning that some characters that appear in [[ASCII]] do not appear in other national variants of ISO/IEC&nbsp;646.

== History ==
[[File:ASCII1963-infobox-paths.svg|thumb|Early ASCII ([[ASA X3.4]]:1963)]]
ISO/IEC&nbsp;646 and its predecessor [[ASCII]] (ASA&nbsp;X3.4) largely endorsed existing practice regarding character encodings in the [[telecommunications industry]].

[[File:ASCII-infobox.svg|thumb|US-ASCII, or ISO/IEC 646:US]]
As ASCII did not provide a number of characters needed for languages other than English, a number of national variants were made that substituted some less-used characters with needed ones. Due to the incompatibility of the various national variants, an International Reference Version (IRV) of ISO/IEC&nbsp;646 was introduced, in an attempt to at least restrict the replaced set to the same characters in all variants. The original version (ISO&nbsp;646&nbsp;IRV) differed from [[ASCII]] only in that code point 0x24, ASCII's [[dollar sign]] ($) was replaced by the [[international currency symbol]] (¤). The final 1991 version of the code ISO/IEC&nbsp;646:1991 is also known as [[ITU&nbsp;T.50|ITU&nbsp;T.50]], International Reference Alphabet or IRA, formerly [[International Alphabet No.&nbsp;5|International Alphabet No.&nbsp;5]] (IA5). This standard allows users to exercise the 12 variable characters (i.e., two alternative graphic characters and 10 national defined characters). Among these exercises, ISO&nbsp;646:1991&nbsp;IRV (International Reference Version) is explicitly defined and identical to [[ASCII]].<ref name="Demchenko_2000"/>

The [[ISO/IEC&nbsp;8859|ISO/IEC&nbsp;8859]] series of standards governing 8-bit character encodings supersede the ISO/IEC&nbsp;646 international standard and its national variants, by providing 96 additional characters with the additional bit and thus avoiding any substitution of ASCII codes. The [[ISO/IEC&nbsp;10646|ISO/IEC&nbsp;10646]] standard, directly related to [[Unicode]], supersedes all of the ISO646 and ISO/IEC&nbsp;8859 sets with one unified set of character encodings using a larger 21-bit value.

[[File:ISO-646-JP-paths.svg|thumb|ISO 646:JP]]
A legacy of ISO/IEC&nbsp;646 is visible on Windows, where in many East Asian locales the [[backslash]] character used in [[filenames]] is rendered as [[¥]] or other characters such as [[₩]]. Despite the fact that a different code for ¥ was available even on the original IBM PC's [[code page 437]], and a separate double-byte code for ¥ is available in [[Shift JIS]] (although this often uses [[Halfwidth and Fullwidth Forms|alternative mapping]]), so much text was created with the backslash code used for ¥ (due to Shift_JIS being officially based on ISO 646:JP, although Microsoft maps it as ASCII) that even modern Windows fonts have found it necessary to render the code that way. A similar situation exists with ₩ and [[EUC-KR]]. Another legacy is the existence of [[C trigraph|trigraph]]s in the [[C programming language]].

== Code page layout ==
The following table shows the ISO/IEC&nbsp;646 Invariant character set. Each character is shown with its [[Unicode]] equivalent. National code points are gray with the ASCII character that is replaced. Yellow indicates a character that, in some regions, could be combined with a previous character as a [[diacritic]] using the [[C0 and C1 control codes#BS|backspace]] character, which may affect [[glyph]] choice.

In addition to the invariant set restrictions, 0x23 is restricted to be either [[Number sign|#]] or [[£]] and 0x24 is restricted to be either [[Dollar sign|$]] or [[¤]] in ECMA-6:1991, equivalent to ISO/IEC 646:1991.<ref name="ECMA-6_1991"/> However, these restrictions are not followed by all national variants.<ref name="ISO-IR-061" /><ref name="ISO-IR-057" />

=== National derivatives ===
Some national character sets also exist which are based on ISO/IEC 646 but do not strictly follow its invariant set (see also [[#Derivatives for other alphabets|§ Derivatives for other alphabets]]):

| ECMA
| [[Honeywell-Bull]]
| Latin-Greek mixed graphics (Greek capitals only).<ref name="Bemer_1980"/> Visually unifies Greek capitals with Latin capitals where possible, and adds the remaining Greek capitals. Unlike the other Greek versions, all Basic Latin letters remain intact. Replaces invariant punctuation as well as national characters, however,<ref name="ISO-IR-027"/> and hence is still not strictly speaking an ISO 646 variant.

| [[Switzerland]] ([[French language|French]], [[German language|German]]) ([[Code page 1021]]<ref name="CP1021"/>) Invariant code point 0x5F is changed from <code>_</code> to <code>è</code>. Is a [[National Replacement Character Set|DEC NRCS]] variant, closely related to ISO 646, but lacks a fully ISO 646 compliant equivalent.

=== Control characters ===
All the variants listed above are solely graphical character sets, and are to be used with a [[C0 control characters|C0 control character]] set such as listed in the following table:

These would be selected by using a mechanism such as [[shift out]] or the NATS super shift (single shift),<ref name="ISO-IR-007"/> or by setting the eighth bit in environments where one was available:

Not actually applicable:
 GR (88, 18, 19) or e.g. KOI-7 - replaces invariant letters with e.g. Greek ones; it would immensely and pointlessly expand this table to include all letters, see separate table later in article for that purpose.
 Katakana (13) - a supplementary (shift out) set for an ISO 646 set, not an ISO 646 set in any way in its own right.
-->
The specifics of the changes for some of these variants are given in the following table. Character assignments unchanged across all listed variants (i.e. which remain the same as ASCII) are not shown.

For ease of comparison, variants detailed include national variants of ISO/IEC 646, DEC's closely related [[National Replacement Character Set]] (NRCS) series used on [[VT220|VT200]] terminals, the related European [[World System Teletext]] encoding series defined in [[ETSI|ETS]] 300 706, and a few other closely related encodings based on ISO/IEC 646. Individual code charts are linked from the second column. The cells with non-white background emphasize the differences from [[US-ASCII]] (also the [[Basic Latin (Unicode block)|Basic Latin]] subset of ISO/IEC&nbsp;10646 and Unicode).

Several characters could be used as [[combining character]]s, when preceded or followed with a [[backspace]] [[C0 and C1 control codes|C0 control]]. This is attested in the code charts for IRV, GB, FR1, CA, and CA2, which note that <code>"',^</code> would behave as the [[Diaeresis (diacritic)|diaeresis]], [[acute accent]], [[cedilla]], and [[circumflex]] (rather than [[quotation marks]], a [[comma]], and an [[caret|upward arrowhead]]) when preceded or followed by a backspace. The tilde character (~) was similarly [[Tilde#Role of mechanical typewriters|introduced as a diacritic]] (˜). This encoding method originated in the typewriter/[[teletypewriter|teletype]] era when use of backspace would overstamp a glyph, and may be considered [[Deprecation|deprecated]].

Later, when wider character sets gained more acceptance, [[ISO/IEC 8859]], vendor-specific character sets and eventually [[Unicode]] became the preferred methods of coding most of these variants.

== Related encoding families ==
=== National Replacement Character Set ===
{{main|National Replacement Character Set}}
The '''National Replacement Character Set''' ('''NRCS''') is a family of 7-bit encodings introduced in 1983 by [[Digital Equipment Corporation|DEC]] with the [[VT220|VT200]] series of computer terminals. It is closely related to ISO/IEC 646, being based on a similar invariant subset of ASCII, differing in retaining <code>$</code> as invariant but not <code>_</code> (although most NRCS variants retain the <code>_</code>, and hence comply with the ISO/IEC 646 invariant set). Most NRCS variants are closely related to corresponding national ISO/IEC 646 variants where they exist, with the exception of the [[Code page 1102|Dutch variant]].

=== World System Teletext ===
{{further|World System Teletext|Teletext character set}}
The [[ETSI|European telecommunications standard]] ETS 300 706, "Enhanced Teletext specification", defines Latin, Greek, Cyrillic, Arabic, and Hebrew code sets with several national variants for both Latin and Cyrillic.<ref name="ets300706"/> Like NRCS and ISO/IEC 646, within the Latin variants, the family of encodings known as the [[ISO/IEC 2022|G0 set]] are based on a similar invariant subset of ASCII, but do not retain either <code>$</code> nor <code>_</code> as invariant. Unlike NRCS, variants often differ considerably from corresponding national ISO/IEC 646 variants.

Some 7-bit character sets for non-Latin alphabets are derived from the ISO/IEC&nbsp;646 standard: these do not themselves constitute ISO/IEC&nbsp;646 due to not following its invariant code points (often replacing the letters of at least one case), due to supporting differing alphabets which the set of national code points provide insufficient encoding space for. Examples include:
* 7-bit Turkmen (ISO-IR-230).<ref name="ISO-IR-230">{{cite iso-ir |title=Turkmen Alphabet |sponsor=Turkmenstandartlary |date=2000-09-14 |number=230}}</ref>
* 7-bit Greek.
** In [[ELOT&nbsp;927]] (ISO-IR-088),<ref name="ISO-IR-088"/> the [[Greek alphabet]] is mapped in alphabetical order (except for the final-sigma) to positions 0x61–0x71 and 0x73–0x79, on top of the Latin lowercase letters.
** ISO-IR-018<ref name="ISO-IR-018">{{cite iso-ir |title=Greek graphic set |sponsor=ECMA |sponsor-link=Ecma International |date=1976 |number=18}}</ref> maps the Greek alphabet over both letter cases using a different scheme (not in alphabetical order, but trying where possible to match Greek letters over Roman letters which correspond in some sense), and ISO-IR-019<ref name="ISO-IR-019">{{cite iso-ir |title=Latin-Greek combined graphic set (capital letters only) |sponsor=ECMA |sponsor-link=Ecma International |date=1976 |number=19}}</ref> maps the Greek uppercase alphabet over the Latin lowercase letters using the same scheme as ISO-IR-018.
** The lower half of the [[Symbol (typeface)|Symbol]] font character encoding<ref name="Apple_Symbol">{{Cite web|url=https://unicode.org/Public/MAPPINGS/VENDORS/APPLE/SYMBOL.TXT|title=Map (external version) from Mac OS Symbol character set to Unicode 4.0 and later}}</ref> uses its own scheme for mapping Greek letters of both cases over the ASCII Roman letters, also trying to map Greek letters over Roman letters which correspond in some sense, but making different decisions in this regard (see chart below). It also replaces invariant code points 0x22 and 0x27 and five national code points with mathematical symbols. Although not intended for use in typesetting Greek prose, it is sometimes used for that purpose.
** ISO-IR-027<ref name="ISO-IR-027"/> (detailed in the chart above rather than below) includes the Latin alphabet unchanged, but adds some Greek capital letters which cannot be represented with Latin-script [[homoglyphs]]; while it is explicitly based on ISO/IEC 646, some of these are mapped to code points which are invariant in ISO/IEC 646 (0x21, 0x3A, and 0x3F), and it is therefore not a true ISO/IEC 646 variant.
** The [[World System Teletext]] encoding for Greek uses yet another scheme of mapping Greek letters in alphabetical order over the ASCII letters of both cases, notably including several letters with diacritics.<ref name="etsgreek">{{citation |url=http://www.etsi.org/deliver/etsi_i_ets/300700_300799/300706/01_60/ets_300706e01p.pdf |pages=121 |section=15.6.8: Greek G0 Set |title=ETS 300 706: Enhanced Teletext specification |publisher=European Telecommunications Standards Institute ([[ETSI]])}}</ref>
* 7-bit Cyrillic
** [[KOI-7]] or Short KOI, used for [[Russian language|Russian]]. The Cyrillic characters are mapped to positions 0x60–0x7E, on top of the Latin lowercase letters, matching homologous letters where possible (where в is mapped to w, not v). Superseded by the [[KOI8-R|KOI-8]] variants.
** [[YUSCII|SRPSCII and MAKSCII]], Cyrillic variants of YUSCII (the Latin variant is YU/ISO-IR-141 in the chart above), used for [[Serbo-Croatian|Serbian]] and [[Macedonian language|Macedonian]] respectively. Largely homologous to the Latin variant of YUSCII (following Serbian [[digraphia]] [[Romanization of Serbian|rules]]), except for [[Љ]] (lj), [[Њ]] (nj), [[Џ]] (dž), and [[ѕ]] (dz), which correspond to digraphs in [[Gaj's Latin alphabet|Latin-script orthography]], and are mapped over letters which are not used in Serbian or Macedonian (q, w, x, y).
** The G0 sets for the [[World System Teletext]] encodings for Russian/Bulgarian<ref name="etsrussia">{{citation |url=http://www.etsi.org/deliver/etsi_i_ets/300700_300799/300706/01_60/ets_300706e01p.pdf |pages=118 |section=15.6.5: Cyrillic G0 Set - Option 2 - Russian/Bulgarian |title=ETS 300 706: Enhanced Teletext specification |publisher=European Telecommunications Standards Institute ([[ETSI]])}}</ref> and Ukrainian<ref name="etsukraine">{{citation |url=http://www.etsi.org/deliver/etsi_i_ets/300700_300799/300706/01_60/ets_300706e01p.pdf |pages=119 |section=15.6.6: Cyrillic G0 Set - Option 3 - Ukrainian |title=ETS 300 706: Enhanced Teletext specification |publisher=European Telecommunications Standards Institute ([[ETSI]])}}</ref> use G0 sets similar to KOI-7 with some modifications. The corresponding G0 set for Serbian Cyrillic{{efn|Labelled "Cyrillic G0 Primary Set - Option 1 - Serbian/Croatian", but includes [[Macedonian language|Macedonian]] letters [[Ќ]] and [[Ѓ]] (but not [[Ѕ]]). A subset of Roman letters, mostly those without homoglyphs in the G0 set, are included in the G1 set (15.6.7 Table 41), including [[S]]/s at 0x6B/7B. Croatian is written in [[Gaj's Latin alphabet|Latin script]].|name=wstmaked}}<ref name="etsserbia">{{citation |url=http://www.etsi.org/deliver/etsi_i_ets/300700_300799/300706/01_60/ets_300706e01p.pdf |pages=117 |section=15.6.4: Cyrillic G0 Set - Option 1 - Serbian/Croatian |title=ETS 300 706: Enhanced Teletext specification |publisher=European Telecommunications Standards Institute ([[ETSI]])}}</ref> uses a scheme based on the Teletext encoding for Latin-script [[Serbo-Croatian]] and [[Slovene language|Slovene]], as opposed to the significantly different YUSCII.
* 7-bit Hebrew, [[SI&nbsp;960]]. The [[Hebrew alphabet]] is mapped to positions 0x60–0x7A, on top of the lowercase Latin letters (and grave accent for aleph). 7-bit Hebrew was always stored in visual order. This mapping with the high bit set, i.e. with the Hebrew letters in 0xE0–0xFA, is [[ISO/IEC 8859-8]]. The World System Teletext encoding for Hebrew uses the same letter mappings, but uses BS_Viewdata as its base encoding (whereas SI 960 uses US-ASCII) and includes a [[shekel sign]] at 0x7B.
* 7-bit Arabic, [[ASMO&nbsp;449]] (ISO-IR-089).<ref name="ISO-IR-089">{{cite iso-ir |title=7-bit Coded Arabic Character Set for Information Interchange |sponsor=ASMO |sponsor-link=Arab Standardization and Metrology Organization |date=1985-01-01 |number=89}}</ref> The [[Arabic alphabet]] is mapped to positions 0x41–0x5A and 0x60–0x6A, on top of both uppercase and lowercase Latin letters.

A comparison of some of these encodings is below. Only one case is shown, except in instances where the cases are mapped to different letters. In such instances, the mapping with the smallest code is shown first. Possible transcriptions are given for some letters; where this is omitted, the letter can be considered to correspond to the Roman one which it is mapped over.
