problem with special characters in solution name and/or path

[tomdewilde]

I have this project where a µ is in solution name and path. The switcher.json file shows the characters ok

{
  "solution": "µCliMat.Expert.sln",
  "mappings": {
    "c8.IO": "../../c8.core/c8.core-dotnet/src/c8.IO/c8.IO.csproj",
    "c8.Security": "../../c8.core/c8.core-dotnet/src/c8.Security/c8.Security.csproj",
    "c8.Updater": "../../c8.core/c8.core-dotnet/src/c8.Updater/c8.Updater.csproj"
  },
  "removeProjects": true
}

but when running DNT to switch to the project I get this error:

DNT (DotNetTools, https://github.com/RSuter/DNT, v1.7.0.0)
Binary: C:\Users\tomdw\.dotnet\tools\.store\dnt\1.7.0\dnt\1.7.0\tools\net6.0\any\dnt.dll

Microsoft.Build.Exceptions.InvalidProjectFileException: The project file could not be loaded. Could not find file 'D:\Git.Planio\c8.æclimat\æCliMat.Expert\?CliMat.Expert.sln'.  D:\Git.Planio\c8.æclimat\æCliMat.Expert\?CliMat.Expert.sln

   at Microsoft.Build.Shared.ProjectFileErrorUtilities.VerifyThrowInvalidProjectFile(Boolean condition, BuildEventFileInfo projectFile, String resourceName, Object[] args)
   at Microsoft.Build.Construction.SolutionFile.ParseSolutionFile()
...

notice how the 'µ' in the folder name is shown as 'æ', where as the 'µ' in the solution name is show as '?'

Thanks for any help

saving the switcher.json file using utf-8 encoding solves this issue
