tekstikodeeringuid

Tekstikodeeringuid, also known as text encoding, refers to the methods used to represent characters and symbols as sequences of bits, which are the fundamental units of digital information. Computers can only understand binary code, so text must be converted into this format for storage and processing. Different text encoding schemes exist, each with its own set of characters and rules for mapping them to numerical values and then to binary.

One of the earliest and simplest encoding schemes was ASCII (American Standard Code for Information Interchange). ASCII uses 7 bits to represent 128 characters, including uppercase and lowercase English letters, numbers, punctuation marks, and control characters. While widely used for English text, ASCII is insufficient for languages with characters outside the English alphabet, such as those with accents or characters from other writing systems.

To address the limitations of ASCII, extended ASCII encodings were developed, using 8 bits to represent 256 characters. These often included additional symbols or characters specific to certain languages or regions. However, the proliferation of different extended ASCII encodings led to compatibility issues.

Modern text processing largely relies on Unicode. Unicode is a universal character encoding standard that aims to represent every character in every writing system, as well as symbols and emojis. Unicode assigns a unique number, called a code point, to each character. Various encoding forms of Unicode, such as UTF-8, UTF-16, and UTF-32, specify how these code points are translated into sequences of bytes. UTF-8 is particularly popular due to its efficiency for English text and its backward compatibility with ASCII. Understanding tekstikodeeringuid is crucial for ensuring that text is displayed and processed correctly across different systems and applications.
