ASCII ( / ˈæskiː / ⓘ 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 devices.
The International Phonetic Alphabet (IPA) consists of more than 100 letters and diacritics. Before Unicode became widely available, several ASCII -based encoding systems of the IPA were proposed. The alphabet went through a large revision at the Kiel Convention of 1989, and the vowel symbols again in 1993. [ 1]
Extended ASCII is a repertoire of character encodings that include (most of) the original 96 ASCII character set, plus up to 128 additional characters. There is no formal definition of "extended ASCII", and even use of the term is sometimes criticized, [ 1][ 2][ 3] because it can be mistakenly interpreted to mean that the American National ...
A code point is a value or position of a character in a coded character set. [10] A code space is the range of numerical values spanned by a coded character set. [10] [12] A code unit is the minimum bit combination that can represent a character in a character encoding (in computer science terms, it is the word size of the character encoding).
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
The Basic Latin Unicode block, [ 3] sometimes informally called C0 Controls and Basic Latin, [ 4] is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8. The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes ...
t. e. ISO/IEC 646 is a set of ISO / IEC standards, described as Information technology — ISO 7-bit coded character set for information interchange and developed in cooperation with ASCII at least since 1964. [ 1][ 2] Since its first edition in 1967 [ 3] it has specified a 7- bit character code from which several national standards are derived.
The first 128 code points (ASCII) need 1 byte. The next 1,920 code points need two bytes to encode, which covers the remainder of almost all Latin-script alphabets, and also IPA extensions, Greek, Cyrillic, Coptic, Armenian, Hebrew, Arabic, Syriac, Thaana and N'Ko alphabets, as well as Combining Diacritical Marks.
