When I was working on my manual tests @tsayao provided a useful tip. If you change the`launch(args)` call in EmojiTest.java to `launch(EmojiTest.class, args)` it's easy to run it from the command line like so:

`java @build/run.args tests/manual/text/EmojiTest.java`

It would be nice if all the manual tests did this, it makes them a lot easier to interact with.
