JEP 400 has moved the JDK to using UTF-8 as the default charset, a long overdue change. So if you create a PrintStream or a PrintWriter without specifying the charset then it will default to UTF-8. The issue that I think we have with javac and a few other tools is that they are creating PrintWriters on PrintStreams where the underlying streams are stdout/stderr and so using the native encoding. There was exploration into special casing this scenario during JEP 400 that was rejected because it complicates the spec and may not be feasible in cases where there are many layers in the onion. If there is resistance to fixing the tools then we might have to re-visit this. Naoto may have more to say on this. ------------- PR: https://git.openjdk.java.net/jdk/pull/5771
