Now, with Unicode 9.0 being imminent and the FontCreator 9.1 update, there are even more Unicode blocks in the Insert Character dialogue that I will never use. It is possible to remove those you don’t need by using this tip, but it would be more user-friendly to have a check-box on the dialogue to hide unwanted blocks. There would also need to be a way to show them again.
You could also use the “Go to Unicode Block” to select the block you need.
One could, but that drop list will also be too long with all the unwanted Unicode Blocks.
