Is there an "invalid chars" option?

[Philip Hallstrom]

Hi all -
	Is there any way to prevent certain characters from being valid in
filenames (other than rebuilding the valid chars and excluding the few
invalid ones) ???

I would like to make it impossible to put the following characters in
filenames:

/, :, $, and a space since unix/macs don't like them much.

Is this doable?

Thanks!
