What are the types of character set?
The most popular types of character encoding are ASCII and Unicode. While ASCII is still supported by nearly all text editors, Unicode is more commonly used because it supports a larger character set. Unicode is often defined as UTF-8, UTF-16, or UTF-32, which refer to different Unicode standards.
How do you encode a character?
An encoding scheme or simply encoding is a way to represent a character in binary. An encoding must follow a specific character set. For example, UTF-8 encoding follows the UTF character set. It uses 8-bit binary numbers to represent a character.
