ASCII (/ ˈ æ s k iː / ⓘ ASS-kee), [3]: 6 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 devic
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

ISCII is an 8-bit encoding. [3]: 4 The lower 128 code points are plain ASCII, the upper 128 code points are ISCII-specific. In addition to the code points representing characters, ISCII makes use of a code point with mnemonic ATR that indicates that the following byte contains one of two kinds of information. One set of values changes the ...

(July 2019) (Learn how and when to remove this message) This article compares Unicode encodings in two types of environments: 8-bit clean environments, and environments that forbid the use of byte values with the ...
As a result, high-quality typesetting systems often use proprietary or idiosyncratic extensions on top of the ASCII and ISO/IEC 8859 standards, or use Unicode instead. An inexact rule based on practical experience states that if a character or symbol was not already part of a widely used data-processing character set and was also not usually ...
The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented typing systems are added.
Extended ASCII is a repertoire of character encodings that include (most of) the original 96 ASCII character set, plus up to 128 additional characters.
Devanagari is a Unicode block containing characters for writing languages such as Hindi, Marathi, Bodo, Maithili, Sindhi, Nepali, and Sanskrit, among others.In its original incarnation, the code points U+0900..U+0954 were a direct copy of the characters A0-F4 from the 1988 ISCII standard.
