Note U+20A0 is not the official euro symbol. 20A0 was intended to be the
euro symbol, but was changed later. The real Euro symbol is U+20AC.

Yes, it does properly convert to the platform default characters. Some
things that can complicate this process on Windoze is that the platform
default encoding is Cp1252 which is the Windoze encoding. But the command
line window is often set to the DOS codepage which is different. That is a
problem with Windoze/DOS not Java.
