Yes, that did it.  Thank you.
No idea how I try everything and overlook the simplest solution, duh.

And, Thank you to everyone else that weighed in as well, definitely
some other options to look into.

Side note:  Anybody know why the period doesn''t have to be escaped?
Like just "." allows the dot to be input, as well as "\."
So, [-\w\_\.\/] works just as [-\w\_.\/].  Why is this?
