![]() 16-bit for UTF-16, 32 bits for UTF-32 and 8-bit for UTF-8). On the other hand UTF-16, UTF-32 and UTF-8 are encoding schemes, which describe how these values (code points) are mapped to bytes (using different bit values as a basis e.g. A character set is nothing but list of characters, where each symbol or character is mapped to a numeric value, also known as code points. ![]() Since there are so many characters and symbols in the world, a character set is required to support all those characters. There are two things, which are important to convert bytes to characters, a character set and an encoding. Now, let's start with what is character encoding and why it's important? Well, character encoding is an important concept in the process of converting byte streams into characters, which can be displayed. On the other hand, UTF-32 is a fixed-width encoding scheme and always uses 4 bytes to encode a Unicode code point. BTW, if the character's code point is greater than 127, the maximum value of byte then UTF-8 may take 2, 3 o 4 bytes but UTF-16 will only take either two or four bytes. UTF-8 uses a minimum of one byte, while UTF-16 uses a minimum of 2 bytes. The main difference between UTF-8, UTF-16, and UTF-32 character encoding is how many bytes it requires to represent a character in memory.
