I have a nfs server on a raspberry pi 3 b+, that share an ext4 directory. The nfs client is a windows 10 computer.
I have a problem with filename characters encoding on client side. All accent characters are displayed badly (I am a french speaker, so some words have character like 'é' or 'è' for example).
My local setting on server side was en_US.UTF-8. I have changed it to fr_FR.UTF-8 but it change nothing. It seems that nfs version used is nfs v3. But I didn't manage to force it to v4. I have tried with a share directory on a ntfs partition, it's work fine and all wharacter well displayed.
Do you know what is the root cause of this type of problem ?
