On windows, the text MüllerMaßen is wrongly displayed in the terminal.
That is caused by the 2 layers of encoding tha does exist in Windows world:
1) The JVM encoding (the default encoding)
2) The cmd.exe encoding.
If these 2 mismatches, then we can end with some characters being wrongly encoded when using the default JVM encoding.

Aesh, WindowsTerminal creates a PrintStream that wraps System.out and rely on the default platform (generally windows-1252) for its encoding. Then the int are sent to System.out.

The hidden property "sun.output.encoding" contains the console encoding to use, if not null, its value could be used when creating the PrintStream.
