What is English half-width format?

English half-width format refers to the character encoding system that uses half the width of a full-width character, such as Chinese, Japanese, and Korean characters. In the English half-width format, each character takes up only one byte of memory, which is half the size of a full-width character. This encoding system is commonly used in computer systems and software applications, and it is essential to know how to switch between full-width and half-width modes.
