Hi @wube
I think it’s such an easy thing to do yourself there’s not really need for ACF to add another setting for it. It would probably be more confusing to “non power user” than helpful to power users 🙂
If you want to simply escape values for a specific field type or perhaps even all of your fields you can use the acf/format_value hook:
