---------- BEGIN SOURCE ----------
FileSystem fileSystem = FileSystems.getFileSystem(URI.create("jrt:/"));
String originalPath = "/modules/\u00E4";

Path path = fileSystem.getPath(originalPath);
URI uri = path.toUri();
String reconverted = fileSystem.provider().getPath(uri).toString();
System.out.println("Result: " + reconverted);
System.out.println("Are paths equal: " + reconverted.equals(originalPath));
