Halfwidth and Fullwidth Forms (Unicode block)

Okay kiddo, so imagine you have a toy box with different types of toys in it. Some are small and take up less space, while others are bigger and take up more space.

In the world of computer language, there are different types of characters that take up different amounts of space. Some characters are full-sized and take up a lot of room, while others are smaller and take up less space.

This is where halfwidth and fullwidth characters come in. Halfwidth characters are smaller and take up less space, while fullwidth characters are bigger and take up more space. They're kind of like toys in a toy box - some are small and some are big.

Now, there's a special language called Unicode that helps computers understand different types of characters from all around the world. And in Unicode, there's a special block of characters that are specifically halfwidth and fullwidth.

So, if you're using a computer program that uses Unicode, you might come across these halfwidth and fullwidth characters. They might look a little different than the regular characters you're used to seeing, because they're either bigger or smaller. But they still do the same job - they help the computer understand what you're trying to say!

So remember kiddo, just like toys can be big or small, characters in computer language can be fullwidth or halfwidth. And they're all important for helping computers understand what we want them to do!
