New candidate JEP: 400: UTF-8 by Default

[Bernd Eckenfels]

Hello,

Thanks for the hint. The question is if this would return UTF-8 after the JEP is implemented or not (should probably be mentioned in the JEP). If it keeps returning the legacy/platform file encoding that would be a good API for my purpose (but sounds like that would be rather confusing in regards to the default constructor)

Hi,
FileReader has a method named getEncoding()
