RFR (JDK11/NIO) 8201276: (fs) Add methods to Files for reading/writing a string from/to a file

[forax at univ-mlv.fr]

Hi Alan,

People do not read the documentation.
So adding something in the documentation about when a method should be used or not is never a solution.

Here the user want a String and provides a charset so you have no way but to decode the content to substitute the line separator.

cheers,
Rémi
