is an essential aspect of computer systems that enables the representation and interpretation of text. and are two widely used character encoding standards. ASCII, which stands for American Standard Code for Information Interchange, is a that includes a range of 128 characters, each assigned a unique numerical value between 0 and 127. The provides a convenient reference to map these characters to their respective decimal, hexadecimal, and s.
As technology evolved and the need for supporting a broader range of characters emerged, Unicode was introduced. Unlike ASCII, Unicode encompasses a much larger character set capable of representing characters from multiple languages and scripts. Unicode assigns a unique numerical value, known as code point, to each character in its repertoire. To store and transmit Unicode characters efficiently, various encoding schemes have been developed. and are two popular Unicode transformation formats.
UTF-8, which stands for Unicode Transformation Format 8-, is a variable-length encoding that can represent any Unicode character using one to four bytes. It is compatible with ASCII and allows the direct interchange of ASCII characters without any modification. On the other hand, UTF-16 uses either two or four bytes to represent Unicode characters. It offers a fixed-length encoding for the Basic Multilingual Plane (BMP) and variable-length encoding for supplementary characters.
