Why not simply retricting chars to isalnum() ones ?
As Bill said that would block things like "-" and "_" which are fine.
Bill also mentioned something about "breaking configs going back to
2.4.x" which is bogus because nothing broke when we started blocking
"/" and "." and ".." in networking device names during the addition of
sysfs support for net devices.
I was mainly referring to if we started to filter it out to isalnum() -
spaces/tab/CR etc. certainly could be filtered. (No idea what would
happen with unicode nbsp or other silly things.)
