How to remove all square brackets from a string?

Can a string contain more than one square bracket?
A string will only ever contain one set of square brackets, e.g.: I want matched to contain ‘some important info’, rather than the ‘ [some important info]’ I currently get. Use grouping. I’ve added a ? to make the matching “ungreedy”, as this is probably what you want. Since javascript doesn’t support captures, you have to hack around it.
