Which means that they, for one, don't use Unicode's "default" for their 
"ToUpper" function?

Or do they get their uppercased names from some geographical names 
database? In which case we would have a large-scale use of ẞ

Worth tracking down if anyone has contacts to that team or know about 
such databases.
