The question pretty much tells the story.
I have a console application I need to run in PowerShell under Windows Terminal. This, due to Windows Terminal solving a bunch of the rendering, code page and other issues one runs into if running PowerShell on its own.
The best idea I can come up with at the moment is to manually create a batch file that would effectively launch the exe crated by Pyinstaller using Windows Terminal. That's my next experiment.
Another --probably crazy-- idea is to wrap the console application in a wxPython application and see if there's a way to render a proper terminal in that context. Probably not the best idea.
