@williamgalas-cp Thanks for contributing! I can definitely see the value here I think but it might not be true that all users of the package would want the content sanitized or at least not sanitized in the same way. Is there a way you think that this could be updated to either make it optional or make it so the specific sanitization(s) that you want to perform are configurable?
