Description

Force the current Powershell session to use UTF8. As we see A LOT of issues with encoding and Powershell will move towards UTF8 in the near™️ future, it might be a good idea to already do so here.

@travistx @lnu thoughts?

@travistx @lnu thoughts?

I've been using UTF8 for a while, and haven't seen any issues. But I only use Windows / Windows Terminal / English. I just did a bit of testing with the default Powershell 7 terminal and Powershell 5.1 and it seemed to behave normally.

Let me check it with powershell on macOS.

=> no issue whatsoever
Maybe a message could be printed when the module is loaded and the encoding changed? so people knows the module changed the encoding, which can affect other unrelated things.

It shouldn't do much weird stuff, but you never know.
