As far as I understand the change it will show tofu'ed characters in their intended appearance (the example is misleading here) but disable the item so it looks differently and cannot be selected.

* The dialog is quite confusing right now. Since the font name is selected after this pseudo-hierarchical organization, along with the font size that is rather a zoom, I would say adding another button is not diminishing the overall UX. Users will basically search and not browse all the fancy characters. And I agree that a split- or menu button is not needed.
* The icon have to be something else, of course. You may ask Andreas Kainz for that.
* For the text you could say "Highlight applicable characters" and "The currently selected font may not include all unicode characters, which will be dimmed when this option is checked.". But take this as just an idea.
* Btw: What will be the default? Suggest On.
* Code: -

+ What happens when you search for something with having the dim feature enabled? I recommend to also not hide but dim those results.
+ How do you discriminate the non-applicable chars from the non-printable?

o Today I can select the alien chars and add them to the clipboard. Perhaps my target has a different font and for some reason I don't want to change it. This workflow will not be supported anymore when the items are disabled. Very far-fetched workflow, however. Just to mention.
