I'm wondering if it is possible to setup Fancy Product Designer Pricing plugin to avoid spaces and question marks from price calculating.
I do not want to charge for spaces.
This is currently not possible. You need to get custom coding for that. If you want to hire us you can do so via www.fancyproductdesigner.com/customization-request
I would also like to see this functionality.
I'm not sure it makes sense to charge for a space when many customers may not consider this a character, rather the lack of one.
You can also open a topic in our feature request forum so we can keep it in mind for further updates. https://support.fancyproductdesigner.com/support/discussions/forums/5000217737
