Why doesn't the Russian language work in the .NET Core console?

Question

.NET

Win 10 + Visual Studio 2017 + .NET 4.6.2 + .NET Core SDK 1.1
All source files in UTF-8.
Similar code for .NET works correctly.
How can this be fixed?

Answer 1

By default, the encoding in the Windows console is 866.
Switch the encoding before outputting.
Or switch the console to UTF-8 mode in the batch file:
chcp 65001
