I currently have multiple deployments with of Freenas and Truenas with a mix of OSX and Windows clients. We constantly have issues with users on OSX systems using illegal characters in filenames but only on our Freenas systems. I have compared the systems and it appears on Truenas all illegal characters appear to Windows users as "". I'm trying to figure out how to mimic this as I have tried mass renaming in the past and have had mixed results.
