What is a graphic character?

graphic character, in computer programming, is any symbol that is part of the predefined character set, but it is not a letter or number. Character set is a sequence of symbols that the computer uses to display data. Characters consist of letters, numbers, punctuation, control characters and graphic symbols. The only element of this set is a graphic feature. There are many pre -defined character sets, each containing a number of graphic characters or none at all.

The complete set of characters is a list of symbols, letters, numbers, and punctuation that the computer can index according to the number of example is in an example that is in the same file. This means that no matter what font is selected, the "A" Index is always the same. All characters that are not numbers or letters, but are known instead as glyphs. These glyphs can be representative of different symptoms and symbols in different industries, or it could only be a collection of trivial shapes. This is becausethat, while the alphanumeric part of the character is strictly defined according to international standards, there is no graphic part.

Originally, the American standard information exchange code (ASCII) was a standard character set for most computers. ASCII characters set all characters above index 127 as a graphic character.

The most common common use of the graphic feature was to draw windows and other cloisters on the screen in text mode. However, the arrival of fully graphical operating systems has removed this need, but these characters have become sparsely used, especially in console applications. As time proceeded, different countries have introduced their own characters, most of which were incompatible.

UNICODE® establishment as an international standard for sign sets unifies all different sets that existed. Unicode® allows much more characters than ASCII, and also reserves space for glyphs and other graphics characters, such as arrows.

There are special characters in the character set, known as control characters that are not visualized on the screen instead of dictating the action the computer is to receive. These include serving, return and backward space. The character for empty space is considered to be a control character and a graphic character, although it does not have a technically visual representation. The space is the only graphic feature that is also a control character.
