Merkistönkoodi, often translated as character encoding, is a system that assigns a unique numerical value to each character in a given set of characters, such as letters, numbers, and symbols. This numerical representation allows computers to store, process, and transmit text data. Without character encoding, digital devices would not be able to understand or display characters correctly.

Different character encoding schemes have been developed over time to accommodate various languages and writing systems. Early encodings like ASCII (American Standard Code for Information Interchange) were primarily designed for English and contained a limited number of characters. As the need arose to represent characters from other languages, more extensive encodings were created.

Unicode is a modern, universal character encoding standard that aims to include all characters from all writing systems, as well as symbols and emojis. It assigns a unique code point to each character. UTF-8 (Unicode Transformation Format - 8-bit) is a popular and widely used encoding that implements Unicode. UTF-8 is a variable-width encoding, meaning that characters are represented using a varying number of bytes, which makes it efficient for both English text and more complex scripts. Other Unicode encodings, such as UTF-16 and UTF-32, exist but are less common for general web use. The choice of merkistönkoodi is crucial for ensuring that text is displayed accurately across different systems and platforms.
