Subject: [PATCH] vfs: fix cache encoding with special characters - #7760

The vfs use the hardcoded OS encoding when creating temp file,
but decode it with encoding for the local filesystem (--local-encoding)
when copying it to remote.
This caused failures when the filenames contained special characters.
The hardcoded OS encoding is now used uniformly.
