Git STDIN not working from PowerShell Integrated Console on Windows PowerShell

[fred-gagnon]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

With the latest update of the PowerShell extension, piping data to git.exe STDIN fails from the PowerShell Integrated Console configured to use Windows PowerShell (version 5.1.19041.1682). For example:

"protocol=https`nhost=myhost.com`nusername=john`npassword=doe`n`n" | git.exe credential approve
fatal: refusing to work with credential missing protocol field

"protocol=https`nhost=myhost.com`n`n" | git.exe credential fill
fatal: refusing to work with credential missing protocol field

The same commands were working as expected from the PowerShell Integrated Console of extension version 2021.12.0, from a regular Windows PowerShell terminal or from the PowerShell Integrated Console of extension version 2022.5.1 configured to use PowerShell 7.2 rather than Windows Powershell.

Thanks, we were able to repro this. @SeeminglyScience tracked down that running [Console]::InputEncoding = [System.Text.UTF8Encoding]::new() "fixes" it, we'll work on a fix into PSES itself.

Thanks a lot @andschwa and @SeeminglyScience for the quick fix !

@fred-gagnon within a few minutes you should be able to update to https://github.com/PowerShell/vscode-powershell/releases/tag/v2022.6.2-preview and this should be resolved!
