Detailed explanation of the functional features of full-width spaces and half-width spaces

Full-width space and half-width space are two common space characters in Chinese and Japanese. They have different functional characteristics in typesetting, text editing and input methods. This article will explain in detail the characteristics and application scenarios of full-width spaces and half-width spaces, helping readers better understand and use these two space characters.
