Unicode (English: Unicode) is a character encoding and display and processing of text in most languages ​​of the world. Each language has a Unicode format. This standard has been compiled in accordance with the global character set and has been published as a book called 'The Unicode Standard'. The latest version of this standard includes more than 110,000 characters and 100 symbols, a set of code diagrams for visual reference, encryption method and a set of character encoding standard, counting character properties such as uppercase and lowercase letters, a set of reference computer data files and a number of related items such as Character details, unicode parity, rendering, order, and two-way display (for correct display of text containing right-to-left scripts such as Arabic, Persian, and Hebrew, and left-to-right scripts). As of March 2019, the latest version is Unicode 12.0. Unicode's success in integrating character encoding has led to its widespread use in software globalization and localization. This standard has been implemented in many recent technologies, including XML, the Java programming language, the Microsoft .NET Framework, and modern operating systems. Unicode can be implemented with different encodings. The most commonly used cryptographs are UTF-8, UCS-2, which is no longer valid, and UTF-16. The UTF-8 encoder uses only 1 byte for encoding in the ASCII standard. The characters in ski encoding are the same in both encodings. This encryption uses up to 4 bytes per character. UCS-2 uses up to 2 bytes for all characters, so it cannot encrypt all characters in the current Unicode standard. UTF-16 extends UCS-2 encoding and uses 4 bytes for the remaining characters.

History and Development

The goal of Unicode is to remove restrictions on the encoding of older characters, such as those defined in accordance with ISO 8859, which are widely used in different countries but are not compatible with each other. Many older encodings have the common problem that they can process bilingual texts (usually with Latin characters and local symbols), but do not allow processing of more than two languages. The role of Unicode in word processing is to provide a unique code for each character instead of an image. In other words, Unicode presents a character virtually, and the task of creating an image (including size, shape, font, or style) of the character
