Question

с какой целью ввели кодировку unicode ,которая позволяет закодировать 65536 различных символов

Answer 1

256 символов стандартного алфавита стало недостаточно (русский, английский и некоторые спец символы). для ютого ввели unicode, где на каждый символ уже отводится 2 байта, с помошью него уже можно закодировать 65536 символов (и арабский и иероглифы и спецсимволы новые, почти все письменные языки и символы)

Answer 2

Introduction

Unicode is a character encoding standard that allows for the representation of a vast range of characters from different writing systems and languages. It was introduced with the goal of providing a universal character set that could support all the characters used in written human communication. The Unicode standard allows for the encoding of 65536 different characters, providing a comprehensive solution for character representation across various platforms and devices.

Purpose of Introducing Unicode

The introduction of the Unicode encoding system served several important purposes:

1. Universal Character Representation: The primary purpose of Unicode was to provide a universal character encoding standard that could represent all the characters used in written human communication. Before Unicode, different character encoding systems were used for different languages and scripts, leading to compatibility issues and difficulties in exchanging text between different systems. Unicode aimed to solve this problem by providing a single encoding system that could represent characters from all languages and scripts.

2. Compatibility and Interoperability: Unicode was designed to ensure compatibility and interoperability across different platforms, operating systems, and devices. By using a standardized encoding system, Unicode allows for seamless exchange and display of text across different systems, regardless of the underlying hardware or software.

3. Future-Proofing: Another goal of Unicode was to future-proof character encoding. As new languages, scripts, and symbols are developed, Unicode provides a framework for encoding and representing these characters. This ensures that the encoding system can adapt and accommodate new characters without the need for major revisions or changes.

4. Support for Multilingual Text: Unicode supports a wide range of languages and scripts, including Latin, Cyrillic, Arabic, Chinese, Japanese, and many others. By providing a unified encoding system, Unicode allows for the representation of multilingual text, making it easier to create and process text that includes characters from different languages.

5. Consistency and Standardization: Unicode provides a consistent and standardized way of representing characters. This helps in data exchange, text processing, and searching, as it eliminates the need for complex character mapping and conversion algorithms.

Conclusion

The introduction of the Unicode encoding system with the ability to encode 65536 different characters was driven by the need for a universal character representation standard that could support all languages, scripts, and symbols used in written human communication. Unicode aimed to provide compatibility, interoperability, future-proofing, support for multilingual text, and consistency in character representation. By adopting Unicode, different systems can communicate and display text seamlessly, regardless of the underlying hardware or software.
