Encoding control

[danunafig]

Hey,
I guess it would be nice to let users control stdout encoding. As long as spawn cannot have "encdoing" , there is an option to support it with runOptions:

async run(userArguments, runOptions = {}) {
++runOptions.encoding = runOptions.encoding || 'utf8';
...
child = spawn(javaExe, javaArgs, spawnOptions);
++child.stdout.setEncoding(runOptions.encoding);
...
