how to put to " char into an array

Hello,

I need to make an array, which contains characters (which cannot be used when saving a file.)
My problem is, that " should be also in this array, but I cannot put an " between ""-s.
Does anybody have an idea, how manage this situation?

This is how I do it:

badChars = Array("/", ".", "\", "$", "'", "-")

Thank you
