Sorry for asking stupid question. My knowledge of cygwin internals lacks.
However, I can see that for every mintty window (and bash) I get a
conhost process running. I assume that it is where the character
setting is stored for non-cygwin processes started from bash.
Again, it is my naive believe, that somewhere there maybe a convenient
place to call SetConsoleOutputCP with argument matching content of the
LANG environment variable.

Even if you do that, it won't help anything at all. Typical windows program
does not expect a change in console code page at all.
If it was designed to use OEM CP, it will output in it regardless of actual
CP.

At the moment I am using ugly 'cmd /c chcp 65001' and it does help.
BTW. this is a solution recommended by cygwin FAQ. I guess I am not
the first one who encounter this inconvenience.

To be specific, IronPython and cpython interpreters are program which
respect CP settings.
Any .net based console application is by default respecting CP settings.
The minimalistic example of such a program:

using System;
namespace encoding_console {
    class Program {
        static void Main(string[] args) {
            Console.WriteLine("\u2192");
        }
    }
}

This is the case. I didn't realized I was messing something up by
editing things by hand. Sorry.
