Fixing MacOS File Names for a NAS

[David Bovill]

Just got a shiny new NAS. Copying over files from USB drives on the Mac and
I come across the old too long / funny character problem... "?" and "/" and
so forth not allowed. I thought this would have been fixed on the Linus
based file servers by now - but not.

Anyone got a solution - there are thousands of files to copy - or a script -
or a reference to figure out all the different chars that needs fixing?
