I have read a lot of posts (almost all of it 4-5 years old) in that manner, and that way I learned that the things with UTF-8 are a little vague for Windows OS. But here is my question anyway. What is the "en_US.UTF-8" equivalent for Windows 10. This is a linux wide chars cin, cout imbuing locale command. Basically I want to input Cyrillic from console, output Cyrillic on console, read and write Cyrillic from and to files. The "en_US.UTF-8" is pretty handy in Linux, but its duplicate for Windows eludes me.
If you need more specifications, go ask me. :)
