Unicode symbols (arrows) in Java -

I want to use the following symbols for the button in my app:

My code here:

  button goToFirstButton = new button ("\ uE318"); Button prevPageButton = new button ("\ uE312"); Button nextPAGE button = new button ("\ uE313"); Button goToLastButton = new button ("\ uE319");  

More results

It looks like \ uE318 and \ u331 are wrong. What should I use instead? I like to use these images for GoToLastButton and goToFirstButton

But I can not find what code I should use.

I would recommend using symbols on buttons instead of special characters, because the ability to display the client The availability of fonts on the workstation can be greatly affected.
