Ok, great. I should be able to get what I need with this. Just have to figure out how to extend the ranges in the last sub to include more valid characters like brackets, etc...

If I want to include a quote can I escape it with a backslash? Like so ' \" '

And will I be able to easily include a single quote (actually a normal ascii apostrophe) with "'" ?

How about allowing square brackets? Need to be escaped I suppose?

Lastly, is the space after the dash you mentioned there to delimit that dash from the rest of the characters? So if I want to include a space character as allowed, can I add it anywhere within the [] ?
