Earlier quoted context omitted.
I am still surprised that the two-character icons which Zoom uses for accounts without profile pictures become "A�" for anyone called "Alice Ørland" or similar. It is even more surprising that Ö, Š, etc. become �, but 文军 shows up fine.
Not so weird when you consider the context. Zoom is an North American company with most (if not all) of it's product/engineering development happening in China. Just reading public information, it seems they have no development teams in the North of Europe nor Eastern Europe, so it's only natural that some character sets ends up better supported than others.
we have UTF8 as a standard nowadays.
