Container Instance seems not to be able to write proper UTF-8 filenames in to a mounted Azure Files share.
It seems not to be possible to write UTF-8 filenames like it is in Azure App Service.
How to reproduce the Problem:
Mount an Azure Files share from a Storage account into an App Service.
Open a shell to the App Service and create a file "äöü-AppService.txt" into the shared directory.
Mount the same Azure Files share into an Container Instance.
Open a shell to the ContainerInstance aswell and create a File "äöü-ContainerInstance.txt" into the same directory.
Have a look at the two files, either from the App Service shell and from the Container Instance shell
Have a third look into the directory from the Storage browser in the Azure Portal
