Summary

When using the PowerShell extension in Visual Studio Code, terminal input via '$Host.UI.PromptForChoice' or 'Read-Host' and pressing any key results in console output that writes the pressed key followed by a lot of unexpected 'e' characters (until the cursor is at the beginning of the next line).

Steps to Reproduce

Use any version of Visual Studio Code between 1.98.x and the recent version 1.102.0 with the respective recent version of the 'PowerShell' extension and execute any code with '$Host.UI.PromptForChoice' or 'Read-Host'.

Example code:

Write-Host "This is a test. 🙂"
Read-Host "Press any key to continue ..."

Known workarounds:

Option 1: Use Visual Studio Code version 1.97.2 or older.

Option 2: When setting 'terminal.integrated.windowsEnableConpty' to 'false' to use WinPTY instead of ConPTY the problem is gone, but with WinPTY there is no UTF/Unicode support.
