@tuxStarElan We have a potential fix for 1.22.1, but we haven't been able to verify our fix yet. Do you know what encoding your files are using?

[sean-mcmanus]

@tuxStarElan This might be fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.22.1, but we don't know for sure yet...
