Add bad chars notification to VSCode problems

[VikingSven82]

Is it possible to make this plugin output bad characters to the built in VSCode problems window? The little warning triangle / exclamation mark in the bottom left.
This would make it easier to see if there are bad chars in your code, rather than having to scroll through it all and look for the red box.
Very useful addon though, just been fighting with a hyphen that's not a hyphen (\u2013 if you want to add it!) and this addon made it much easier to find the same problem in my other PowerShell scripts.

I will work on it as soon as possible. I'm bit busy, I encourage you to fork this repo & add the feature if you need it quickly :D.

I might give it a try this week, based on https://code.visualstudio.com/api/references/vscode-api#DiagnosticCollection
