Helium Scraper

How can I use a starting url (that contains the character ?) in the command line? Something like this:

"C:\Users\{User Name}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Helium\Helium Scraper.appref-ms" "C:\Users\{User Name}\Desktop\file.hsp?--starting-url=http://www.example.com/link.html[b]?som ... some_value[/b]&--auto-save=true&--auto-close=true"

It doesn't seem to work (because of that ? in the url). The example is taken from here, but modified. Thanks!
