[Console]::OutputEncoding doesn't work to parse exe with unicode output #10789
Description
Steps to reproduce
I have a Windows executable that produces unicode (utf-16) output. In PowerShell 5.1, I can set the [Console]::OutputEncoding property so the output of that command gets correctly interpreted. On PowerShell Core 6.2.3, that doesn't appear to work.
I've also tried setting [Console]::InputEncoding and $OutputEncoding, but the problem persists.
For example, I use the wsl.exe binary here, so this should repro on any system that has the Windows Subsystem for Linux installed.
[Console]::OutputEncoding = [System.Text.Encoding]::Unicode
wsl.exe --list -v | ForEach-Object { $_ }Expected behavior
PS C:\Users\svgroot> [Console]::OutputEncoding = [System.Text.Encoding]::Unicode
PS C:\Users\svgroot> wsl.exe --list -v | ForEach-Object { $_ }
