What is the code point?

The code point

refers to a specific numeric value that means any individual character in the character set. From the end -user point of view, writing on a computer is quite simple; Press the key marked on the keyboard creates a corresponding character on the screen. From the computer point of view, however, writing is much more difficult. The keyboard inputs must be translated several times to create a specific selected character. The code point of a particular character is only one step along the translation string, resulting in a visible text on the screen in a certain set of characters.

characters set is like a multilingual dictionary that explains to a computer that matches which characters. The code point is the number corresponding to the particular character in this character set. Examples of character sets commonly used on computers include American standard information exchange code (ASCII) and Unicode. Each of these sets has a Different set of code points, so while for example, the code 400 in ASCII can refer to "!" Character, in UnicoDE could refer to "&".

As soon as the end user presses the button on the keyboard, the hardware generates a specific set of electronic pulses that the computer acts to convert to binary. Binary is the language of computers that consist of anything other than the characters "1" and "0". From this, the computer calculates a specific number, which must then respond against the code set for generating the intended character. Only after it all creates a computer selected on the screen.

code points are stored on a computer in spaces from one to four bytes. This is a very small piece of memory, which means that the storage of hundreds or thousands of code points is not a real challenge for modern computers. As a result, the manufacturers of the character sets often leave a large amount of space open for unspecified assignment of the code point point, allowing programmers to add other characters to the set,without performing a substantial revision of the code.

The next point worth mentioning is that code points are most commonly used for abstract or non -standard characters in the character set. To view the example of these abstract characters, open the "Start" menu on your computer-if you use a Windows-A computer in "Start Search", "Charmap". Press "Enter" to display a list of available abstract characters for a selected set of characters.
