ASCII: Difference between revisions

Despite being an American standard, ASCII does not have a code point for the [[Cent (currency)|cent]] (¢). It also does not support [[English terms with diacritical marks]] such as [[résumé]] and [[jalapeño]], or [[proper nouns]] with diacritical marks such as [[Beyoncé]].

The American Standard Code for Information Interchange (ASCII) was developed under the auspices of a committee of the American Standards Association (ASA), called the X3 committee, by its X3.2 (later X3L2) subcommittee, and later by that subcommittee's X3.2.4 working group (now [[INCITS]]). The ASA later became the United States of America Standards Institute (USASI)<ref name="Mackenzie_1980"/>{{rp|211}} and ultimately became the [[American National Standards Institute]] (ANSI).

The X3 committee made other changes, including other new characters (the [[brace (punctuation)|brace]] and [[vertical bar]] characters),<ref>Report of Meeting No. 8, Task Group X3.2.4, December 17 and 18, 1963</ref> renaming some control characters (SOM became start of header (SOH)) and moving or removing others (RU was removed).<ref name="Mackenzie_1980"/>{{rp|247–248}} ASCII was subsequently updated as USAS X3.4-1967,<ref name="ASCII-1967"/><ref name="Winter_2010">{{cite web |title=US and International standards: ASCII |url=http://homepages.cwi.nl/~dik/english/codes/stand.html#ascii |author-first=Dik T. |author=Winter |date=2010 |orig-year=2003 |url-status=dead |archive-url=https://web.archive.org/web/20100116001012/http://homepages.cwi.nl/~dik/english/codes/stand.html#ascii |archive-date=2010-01-16}}</ref> then USAS X3.4-1968,<ref name="ASCII-1968">{{cite tech report |title=USA Standard Code for Information Interchange, USAS X3.4-1968 |url=https://archive.org/details/enf-ascii-1968-1970/ |publisher=[[United States of America Standards Institute]] |date=October 10, 1968}}</ref> ANSI X3.4-1977, and finally, ANSI X3.4-1986.<ref name="ASCII-1986"/><ref name="Salste_2016">{{cite web |title=7-bit character sets: Revisions of ASCII |author-first=Tuomas |author-last=Salste |publisher=Aivosto Oy |date=January 2016 |id={{URN|nbn|fi-fe201201011004}} |url=http://www.aivosto.com/vbtips/charsets-7bit.html#body |access-date=2016-06-13 |url-status=live |archive-url=https://web.archive.org/web/20160613145224/http://www.aivosto.com/vbtips/charsets-7bit.html#body |archive-date=2016-06-13}}</ref>
