ASM - Best way to filter out requests containing tilde ~ character?

For PCI, they don't like IIS accepting requests with Tilde (~) characters.   I'm presuming ASM is the perfect place to apply a fix for this, can someone help?

This answer is pulled off of a 12.1.0 box (simply because that's what I have up at the moment), but you can disallow characters here:

 

Security ›› Application Security : Parameters : Character Sets : Parameter Value

 

tilde appears to be disallowed by default.
