What is the difference between full-width and half-width input methods?

php editor Xinyi is here to explain the difference between full-width and half-width input methods. When using computers, we often encounter the concepts of full-width and half-width. A full-width character means that a character occupies the same space and width, similar to the width of a Chinese character; while a half-width character means that a character occupies only half the space and width of a full-width character, similar to the width of an English character. In the input method, switching between full-width and half-width can affect the display and typesetting effect of the input characters, so understanding the difference between full-width and half-width is very important for the correct use of the input method.

Any punctuation mark can be used in half-width state, and there are no special restrictions on spaces. In the full-width state, the function of the space bar changes. After switching to the full-width state and pressing the space bar, we will find that the distance between characters becomes large, and this gap is more obvious than in the half-width state. In addition, the display of English letters is also different in the full-width state. In the half-width state, the typed English letters are of normal size. However, once we switch to full-width mode, we will find that the typed English letters become bold and enlarged.

In full-width state, one letter occupies two characters; while in half-width state, one letter occupies only one character.

Full-width refers to letters, numbers and other characters with the same width as Chinese characters, while half-width means that the width of letters, numbers and characters input when there is no Chinese character input method is half-width.

4. When the Chinese character input method appears, the input letters and numbers default to half-width, but the punctuation defaults to full-width, which can be changed by clicking the corresponding button on the input method toolbar with the mouse.
