The console encoding used when running or debugging a program automatically matches the encoding of the program being run or debugged. For example, your Java program's (or Java project's) encoding will be used by the console and a corresponding VM argument (for example, "-Dfile.encoding=UTF-8") will be added to the command line. This makes it simpler to run and debug code displaying console output.
