If you have the jar in your class path / project path hit CTRL-SHIFT-T and type the name … the jar will be displayed at the bottom. If you haven’t the class in your build path a) put together a dummy project containing all the jars b) I think there is a plugin to find … Read more
When you open a file for reading, you need to explicitly specify the encoding you want to use for reading the file: Reader r = new InputStreamReader(new FileInputStream(“myfile”), StandardCharsets.UTF_8); Then the value of the default platform encoding (which you can change using -Dfile.encoding) no longer matters.
