For example, the capital letter "A" in the Latin alphabet might be represented by the code point 65. The concept of "coded character set" can also be thought of as a function that maps characters to code points. The repertoire may be closed, where no additions are allowed without creating a new standard, as it is the case with ASCII and most of the ISO-8859 series, or it may be open, allowing additions, as it is the case with Unicode.Ī collection of characters used to represent textual information, in which each character is assigned a numeric code point. #ASCII CODEPOINTS FULL#Depending on the encoding scheme used, characters may be represented with different code units - sequence of bits used to represent a single character.Ī character repertoire is the full set of abstract characters a system supports. In Unicode, the character is the basic unit of encoding. It is also referred to as abstract character. In the context of an encoding convention, the term "character" refers to the abstract meaning, rather than a specific shape ( glyph), though in code tables some form of visual representation is also essential for the reader’s understanding. Common character encoding standards are US-ASCII, Extended ASCII, Unicode and UCS.Ī character is the smallest component of a written language that has semantic value. Depending of the character encoding convention used, the same text will end up with different binary representations.
