Definition

Noun: A defined collection of distinct symbols, such as letters, numbers, punctuation marks, and other graphical elements, used to represent textual information in a computing or telecommunications system. It establishes a complete set of characters available for encoding.

Usage

A character set is a fundamental specification that maps abstract characters to numeric codes (code points). It defines the repertoire of characters a system can recognize and process. * Early computers used the ASCII character set, which includes 128 characters for English. * Modern applications often use the Unicode character set, which aims to include every character from all the world's writing systems. * When you save a text file, you may need to specify the correct character set, like UTF-8, to ensure all symbols display properly.

Advanced Usage

• Character Set vs. Character Encoding: While often used interchangeably in casual conversation, technically a character set defines the of characters, while an (like UTF-8 or ISO-8859-1) defines the rules for how those characters are represented as bytes for storage or transmission. Unicode provides a character set and several encodings for it.
• Declaring a Character Set: In web development, the character set for an HTML document is declared within the tag (e.g., ) to instruct the browser how to interpret the bytes of the page.
