The character formation that is used by computers is not understandable for humans. Therefore, digital devices store information in the form of numbers and text to make them readable. In this scenario, for defining the code, the Unicode uses a character encoding system to make things readable. Character encoding is highly indispensable because there’s a need to display the same information on every device. Many people argue that custom encoding is more flexible, but the truth is another way around. However, it will create several problems; the information will not be displayed in the same pattern on different devices. 

What is Character Encoding?

A number is assigned to every character to make it usable. Industry standards have been set for creating a more flexible environment for everyone. To make information displayable in the same way, there’s a common character encoding scheme. 

How is Unicode Formed? 

The first widespread encoding scheme is none other than ASCII (American Standard Code for Information Interchange). The encoding system is only confined to 128 characters. However, the encoding system is perfect for English, as it covers all the alphabets, numbers, and punctuations, but it isn’t compatible with other languages. Therefore, here comes the need for the same encoding scheme for the characters of other languages to be covered. For that reason, developers around the world started to develop their own encoding schemes. In the end, the entire situation turned out to be a bit messy. It was an arduous chore to figure out which encoding scheme is the more suitable one, and there were also issues regarding configuration. Therefore, it was obvious that a new character encoding scheme was the need of time to create a standard formation for all the languages. The main purpose of Unicode is to unify all the character encoding schemes. Along with that, there was a need to end the confusion between the computers. There are around 128,000 characters and can be seen on the Unicode consortium. 

Code Units 

Code units are used to form the encoding schemes. An index is described for knowing where our character is positioned on a plane. A code unit contains 16-bits. Along with that, the code units can be transformed into code points. There are different formations of Unicode, and all of them differ slightly from each other. 

How Unicode Solved the Information Exchange Problem? 

There was a need to fix the matter of solving the information exchange issue. It was also the need for time to solve issues of different writing systems. Unicode was the solution, and that is the reason it is prevailing in the current scenario. There are bigger spaces utilized for encoding characters. There are 8-bit, 18-bit, and 32-bit values. You can say that Unicode is a superset of ASCII. However, Unicode has its own unique code value. In Unicode, there is no issue of showing the wrong glyph on the plane. Therefore, the text of any writing system can be mingled with another language. The step enabled the devices useful around the globe. Now, the misinterpretations of code and writing systems are a matter of the past. There won’t be any webpage that will be using the old system of the encoding scheme. 


In the last analysis, Unicode has truly revolutionized the entire spectrum of writing systems. It has enabled us to eradicate all the confusions and hurdles of the past. Therefore, the character encoding scheme is making things easier and faster. Above all, the exchange of information was a serious issue, but now the entire problem has been solved with the inception of the Unicode character encoding system.
