Illegal re-direction attempt for a domain name with question mark query "?"

Hi, we are implementing ASM in our company and see that the ASM is blocking requests made for the domain name, say for example - m.abc.com?. This is because some user searched the company name from his phone in google and then the web-app-servers re-directed it to the mobile-app servers. I am not able to add the question mark "?" in the domain name in the policy as it gives me an error "please enter a valid redirection domain name". Is there a way to get around this other than completely disabling the violation.?
