There's something to that - spaces in filenames are a big headache.  But 
in this case it's a settled question - it's not something that "other 
systems" do, but something that is already supported in FreeBSD: 
getfsent(3) allows an fstab to have escaped characters in path names, so 
jail(8) should as well.  If I could just use getfsent(3) myself this 
would never have come up, but my need to operate in in-memory strings 
instead of a file made that inconvenient.  Fortunately it just called 
strunvis(3) which is trivial to add.
