What is the encoding used by ASCII character set?

Question

I know UNICODE character set follows the UTF encoding style. But does ASCII character set follow any encoding style?

I'm confused. In C++ if you use wchar_t , it will use UNICODE character set with a UTF-16 encoding, is what I read. So is there any similarity with ASCII set? Or ASCII is an encoding itself? If yes then what character set does it use? — Zeph_The_Hungry_Loli

ASCII is a subset of unicode, see basic latin in unicode thats the ASCII subset — zoomlogo

@PyGamer0 Other way around. UTF is a superset of ASCII. ASCII came first. OP: see en.wikipedia.org/wiki/ASCII — NathanOliver

@Zeph_The_Hungry_Loli wchar_t is not any specific encoding, it's just 16-bit characters in whatever encoding you put there. Or just 16-bit numbers. — molbdnilo

Unicode, formally, is the Standard. It can be implemented by different character encodings. The Unicode standard defines Unicode Transformation Formats (UTF): UTF-8, UTF-16, and UTF-32, and several other encodings. UTF-8 uses one to four bytes per code point and, being compact for Latin scripts and ASCII-compatible. The first 128 code points represent the ASCII characters, which means that any ASCII text is also a UTF-8 text.
