File names with 'weird' character sequences don't backup

I keep getting the following error every backup:

HT: Error getting free space for path “/mnt/backups/client.local/160911-0348/Users/username/Library/Application Support/TextMate/Managed/Bundles/Source.tmbundle/Snippets/Escaped Single Quote Pair: ‘…’.plist”

I think the … in the filename is screwing up some things. Anyone have a solution (that doesn’t involve renaming the file)?

The server is backing up from a 500GB HFS+ volume to a 10TB EXT4 volume on Linux.
