> Okay, and also when GetConsoleCP() fails because there's no console (e.g. python.exe w/ DETACHED_PROCESS creation flag, or pythonw.exe). 

When there is no console, stdio should use the default textio encoding that is ANSI for now.

> However, using UTF-8 for the input code page is currently broken in many cases, so it should not be promoted as a recommended solution until Microsoft fixes their broken code (which should have been fixed 20 years ago; it's ridiculous). Legacy console applications rely on ReadFile and ReadConsoleA. Setting the input code page to UTF-8 is limited to reading 7-bit ASCII (ordinals 0-127). Other characters get converted to null bytes.

Regardless when we promote it, people use `chcp 65001` in cmd and `[Console]::OutputEncoding = [Text.Encoding]::UTF8` in Power Shell.
In such situation, UTF-8 is the best encoding for pipes and redirected files.
