skaffold destroys umlauts

skaffold v2.13.2 on Windows 10 destroys umlauts that appear in the build log output. This happens for jib, maven and even for simple things like custom buildCommand command like

echo "Hallo Überschall"

which becomes

\"Hallo �berschall\"

The Google Cloud Code plugin in IntelliJ stops filling the console the moment it hits such a broken output line. So using skaffold through the Google Cloud Code plugin, you cannot see any build results or logs after the broken line.

I have not found a way to configure encoding for skaffold or fixing this problem in any other way.
