What’s ASCII?

Text encoding standard for electronic communication, limited to 128 code points. ASCII (/ˈæskiː/, ASS-kee), an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. ASCII has just 128 code points, of which only 95 are printable characters, which severely limit its scope.
