ASCII Unicode
Character Encoding Code Point
Character Set ASCII Table
UTF-8 UTF-16

 

A character encoding standard that assigns a distinct numerical value to each character. A character encoding standard that is used to depict text in computers and other devices.
A unique number is assigned to each character in Unicode. The process of assigning a numerical value to each character is the act of giving a specific numeric representation to each character.
A visual representation, presenting the characters and their corresponding values, is known as a chart used to denote ASCII encoding. A grouping of symbols or letters that a computer or software can utilize.
A character encoding for Unicode utilizing 16-bit code units. A character encoding system known as variable-length encoding utilizes 8-bit code units to represent Unicode characters.
