Proxima nova uppercase ẞ (eszett)

So in further investigation ẞ (capitalised) is supported but ß (lowercase) does not change to this variant when using text-transform:uppercase and displays SS instead, inversely ẞ (capitalised) does change to the lowercase variant when using text-transform:lowercase.
