Oh, you're confusing UCS-2 with UTF-16, UCS-2 is a subset of UTF-16
that only handles the basic plane. Just like no-one is surprised that
UTF-8 handles more than 256 characters, it shouldn't surprise you that
UTF-16 handles more than 65536. ICU hasn't used UCS-2 since 1996.

It's in the FAQ:

Have a nice day,
