Title: Please change javadoc encoding to UTF-8 for asian developer

I'm a big fan fo vert.x. however when i'm about to build vertx-platform javadoc task with eclipse, it was failed with the following message

[sts] -----------------------------------------------------

It was because of the character '£' , it was not encoded ASCII.
So i propose to change javadoc encoding to UTF-8.

Please approve this pull request for better develop environment. thanks
