Expand usable characters especially ? and # in Custom Query Parameters in ULP

Feature: Relaxing the regular expression for ext- params.


Currently, Custom Query Parameters are validated by the following regular expression and any characters do not match this expression cannot be used.

  • /^[-\w.*~@+ /:]{1,255}$/

In addition, since this behavior is not documented, I think it should be explicitly stated here.


We pass the privacy policy and terms of use URLS to ext- params and ULP displayed them as they are.
Currently, ext- params doesn’t accept # and ? so we can not set urls including them.
