Answer 1

You are (most likely) reading the text correctly, but when you write it out, you also need to enable UTF-8. Otherwise every character that cannot be printed in your default encoding will be turned into question marks.

Try writing it to a File instead of System.out (and specify the proper encoding):

Writer w = new OutputStreamWriter(
   new FileOutputStream("x.txt"), "UTF-8");

Answer 2

If you are reading the text properly using UTF-8 encoding then make sure that your console also supports UTF-8. In case you are using eclipse then you can enable UTF-8 encoding foryour console by:

Run Configuration->Common -> Encoding -> Select UTF 8

Here is the eclipse screenshot.
