I'm trying to redirect unicode in the windows console, but when redirecting, empty files are created. If i do it without redirects, then the text is displayed correctly in the console:

import core.sys.windows.windows;
import std.stdio;

void main() {
    wstring str = "Just text...";
    HANDLE h_stderr = GetStdHandle(STD_ERROR_HANDLE);
    HANDLE h_stdout = GetStdHandle(STD_OUTPUT_HANDLE);
    WriteConsoleW(h_stderr, str.ptr, cast(DWORD)str.length, NULL, NULL);
    WriteConsoleW(h_stdout, str.ptr, cast(DWORD)str.length, NULL, NULL);
}

.\app.exe 1> stdout.txt 2> stderr.txt

Just found this on the net. Hmm... I didn't know that Windows has its own nuances in working with threads. Thanks for the tip.

The redirection issue has been resolved. Another one has now emerged. Since I have unicode, I need to write 2 bytes each, which is exactly what happens. In this regard, incorrect output to the file. How to convert it otherwise? Or does it not depend on the output?

import core.sys.windows.windows;
import std.stdio;
import std.utf;

void main() {
    wstring str = "Это тестовый текст";
    HANDLE h_stderr = GetStdHandle(STD_ERROR_HANDLE);
    switch (GetFileType(h_stderr)) {
        case FILE_TYPE_CHAR:
            WriteConsoleW(h_stderr, str.ptr, cast(DWORD)str.length, NULL, NULL);
            break;
        case FILE_TYPE_PIPE:
            auto utf_str = str.toUTF8;
            WriteFile(h_stderr, utf_str.ptr, cast(DWORD)utf_str.length, NULL, NULL);
            break;
        default:
    }
}

output:

Strange. Everything works correctly on the command line. And the file redirection works and 2>&1 works. But in PowerShell it gives errors. Moreover, PowerShell reacts to FILE_TYPE_PIPE, and CMD reacts to FILE_TYPE_DISK.
