> Please review this small fix to Windows system property init code. This is leftover from the support for `Console.charset()` method, where it lacked to initialize `sun.stdout/err.encoding` to `UTF-8` for the code page `cp65001`.  The fix has been manually verified, but no automated test case is provided, as automatically setting `UTF-8` for the system locale on Windows test machine seems not possible.
