What is the difference between the full width and half width in the Pinying input method, and what i

1, the full-width occupies a larger place than 2, and the full-width and half-width are different when you lose the symbol.

A full-width character occupies two bytes, and a half-width character occupies one byte.

Full Width - Refers to one character occupying two standard character positions.

Half-width - Refers to a character that occupies a standard character position.

That is, what we usually see, full-width symbols are usually larger, and the difference between the small full-width half-width half-width in the English letter and the symbol is the easiest to see, for example: half-width: wwwww, full-width: wwww,

The difference between full-width and half-width is the difference between Chinese characters and English characters.

The invention and use of computers originated in Western countries, and the basic character set (ASCII) was first defined by the 26 English letters and some specific common symbols, which occupy one byte of space per character.

However, Chinese (similar to Japanese, Korean, etc.) is not based on English letters, and its font size is much larger than 256, so it is stored in two bytes instead.

To show the difference, the latter (Chinese characters) are usually called full-width symbols, and the former are called half-width symbols.

The switching of full-width and half-width of the input method is the switching of the output characters Chinese and Western (or directly, the switching of 2 bytes and 1 byte). You can open any text software (such as Notepad) and view the output results of the same letter in full-width and half-width respectively, and you can find the difference:

Characters (letters, punctuation, and so on) entered in half-width take up half the width of the text entered in full-width mode.

The full-width occupies two bytes, and the half-width occupies one byte.

Half-width full-width is mainly for punctuation, full-width punctuation occupies two bytes, half-width occupies one byte, and whether it is half-width or full-width, Chinese characters still have to occupy two bytes.

Only half-width punctuation can be used in the source of the programmer (excluding data inside the string).

On computers that don't support languages such as kanji, you can only use half-width punctuation (in fact, there is no such thing as half-width full-width in this case).

Other times, it seems that there is basically no distinction between full-width and half-width, so you can use whichever you think is good-looking.
