The term DBCS traditionally refers to a character encoding where each graphic character is encoded in two bytes.. In an 8-bit code, such as Big-5 or Shift JIS, a character from the DBCS is represented with a lead (first) byte with the most significant bit set (i.e., being greater than seven bits), and paired up with a single-byte character-set (SBCS).
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
An abstract character repertoire (ACR) is the full set of abstract characters that a system supports. Unicode has an open repertoire, meaning that new characters will be added to the repertoire over time. A coded character set (CCS) is a function that maps characters to code points (each code point represents one character). For example, in a ...
Infobox template for character encodings, character sets, code pages et cetera. While the difference between a coded character set and a character encoding is clear in a Unicode context (UTF-8 and UTF-16 are different encodings for the same set), the difference is often blurred immensely by legacy encodings. For example, so-called "WinLatin-1" is a de facto extension of the "Latin-1" (ISO 885

As first introduced in 1991 had 16 bits; extension to 21 bits came later.
ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.
The category of character sets includes articles on specific character encodings (see the article for a precise definition). It includes those used in computer science (coded character sets (also known as character sets (this term should not be used anymore [according to whom?]) or code pages), character encoding forms, character encoding schemes) and those that use non-numeric, pre-digital ...
