How UTF-8 represents more than 256 characters and when to use UTF-16?

How UTF-8 represents more than 256 characters and when to use UTF-16?

We all know what character encoding is. Like the simple ASCII 7 bit used for normal 128 characters representing and UTF-8 for representing 256 characters.
I have 2 questions:
Some people saying UTF-8 can represent more than 256 characters. How this is possible?
When to use UTF-16? Like which condition e.g. if we have to use Japanese or some other language?
