What is a full width character? How do I enter a full width symbol?

Generally, characters occupy 1 byte, that is, half width, and a word occupies 2 bytes, that is, full width!

Double-width characters are allocated two bytes of space to store this character!

The full-width should be two characters.

Half-width occupies one.

Whatever, huh.

Full Width; A computer character.

Full-width is a type of computer character, and each double-width character occupies two standard (or half-width) positions.

Each normal character (or half-width character) occupies only one byte of space (a byte has 8 bits and a total of 256 encoding spaces), while the number of hieroglyphic languages such as Chinese, Japanese, and Korean is much larger than 256, so two bytes are used instead. At the same time, it is also because of the writing habits of Chinese, Japanese, Korean and other hieroglyphs, if you use full-width characters uniformly, the arrangement will also look neat.

For neat arrangement, characters and punctuation in English and other Latin are also available in full-width format.

Chinese characters, English characters that specify full-width, and graphic symbols and special characters in the national standard GB2312-80 are full-width characters. Typical system commands do not use double-width characters, and only use double-width characters for word processing.

In the Chinese input method, the shortcut key to switch between full-width and half-width format is shift+space.

Full width of numbers and Latin letters:

Full-width symbols-- means that one character occupies two standard character positions.

Chinese characters and English characters with full-width characters, as well as graphic symbols and special characters in the national standard GB2312-80 are full-width characters. Typical system commands don't use double-width characters, and only use double-width characters for word processing.

Here's how to determine that the input text or symbol is full-width is as follows:

1. Half-width characters or symbols occupy one character, and full-width characters occupy two. First of all, the difference in punctuation is the world auction, as shown in the figure below, English punctuation is basically all about occupying only one character.

Second, as shown in the figure below, the punctuation marks in Chinese are basically full-width (except for individual symbols, such as: "—).

3. Look at the English alphabet again, the English alphabet generally only occupies one character and is very compact.

Fourth, if you use mountains for full-width input, there is a large spacing between each letter.

Fifth, the last is Chinese characters, as shown in the figure below, it can be seen very straightforwardly that each Chinese character occupies two characters, which is the same as the width of the two English letters.

You can tell if a character is half-width or full-width by using the following method:

1.According to the character encoding range: In Unicode encoding, half-width characters (English letters, numbers, punctuation marks, etc.) are usually located in the range of U+0020 to U+007E, and full-width characters (Chinese, Japanese, Korean, etc.) are usually located in the range of Unicode encoding.

2.Count the number of bytes of a character: In ASCII encoding, a half-width character occupies one byte, while a full-width character occupies two bytes. Therefore, you can count the number of bytes occupied by a character to determine whether it is half-width or full-width.

3.Use the character width function: Different programming languages or texters may provide a character width function that can be used to determine whether a character is half or full width. For example, in Python, you can use the function to determine this.

It is important to note that there are some characters that may be both half-width and full-width, depending on the specific character envy set and font settings. When judging character width, it's a good idea to use a character width standard or character handling function that is consistent with the target usage scenario to ensure accuracy.

It's important to note that the methods used to determine half-width and full-width characters may vary across different programming languages, operating systems, and devices, so the implementation may vary. In practice, you need to choose the method that best suits your needs based on your specific situation.

Open a word blank document, and then find the small box in the lower right corner of the input method, click the small arrow down on the right side of the small box, click "full half width", and then click "moon", when the "moon" in the input method becomes "sun", the last symbol becomes a full-width symbol.

Full-width and half-width are relative to the input method and occupied characters, mainly when entering Chinese, commas, periods and other punctuation spring shade round symbols use full-width mode to occupy Chinese characters, occupying 2 characters.

The half-width is the English jumble mark, which occupies 1 character. When writing English materials, if you use full-width and the other party's computer does not have Chinese support, the punctuation marks you see are only some squares, and half-width will not have such a problem.
