Doesn't seem to work for me.

The exact code I tested:
----
import std.stdio;
import std.exception: enforce;
import core.sys.windows.windows;

void main()
{
SetConsoleCP(65001);
SetConsoleOutputCP(65001);

uint readBytes;
ubyte[4] c;
ReadFile(GetStdHandle(STD_INPUT_HANDLE), c.ptr, c.length,
&readBytes, null).enforce();
writeln(readBytes, " ", c[]);
}
----

When I enter "a", it prints "3 [97, 13, 10, 0]".
When I enter "ä", it prints "0 [0, 0, 0, 0]".

I've also tried even larger buffers. Same result.
