I have a form that is filled out without regard to special characters. This means that quotation marks, slashes, and many other characters which raise hell with HTML and CGI's will be typed in.

This information will be used both to return a HTML page with another form (including HIDDEN INPUTS where the quotation marks raise problems) and to generate a plain text email. Then the form will be submitted and an HTML page will be generated which requires the quotation marks to appear again.

I have no problem dealing with returns and paragraphs, but was wondering if there is a module that will handle all possible input characters that would cause problems (especially quotation marks) when generating HTML from the input.
