I went to the Registry Editor and checked.
Here is a registry key "Use Old Fonts". See its exact location in the attached image.
I wonder what happens if you set its value to "1", restart ARCHICAD.
Will it change all fonts to how they looked in previous versions?
Or will it solve this font issue you are showing?
Please let us know if you decide to test it.
