如何在 WPF 应用程序中将 UTF-8 写入控制台

Question

I have a WPF application that also writes to stdout because it can operate in two modes, UI or console. The output contains non-ascii characters, eg

Console.WriteLine("ÀÁÂÃÄÅÆ ®¯°±¹²³¼½¾¶·")

The result is a stream that I can redirect into a file and the file is encoded as ISO-8859 but I want it to be UTF-8 .
For console applications this answer suggests to set

Console.OutputEncoding = System.Text.Encoding.UTF8;

But when I do that in my application I get

System.IO.IOException "The handle is invalid" when setting OutputEncoding

Answer 1

as pointed out by JosefZ:
There's a checkbox since Windows 10 insider build 17035 for setting the locale code page to UTF-8:

Control Panel > Cloc and Region > Region > Administrative > Change system locale... > Beta: Use Unicode UTF-8 for worldwide language support = true
