I'm wondering how to display simplified and traditional chinese characters through Java in Dreamboard and on lockscreen mods.

Also, how to add a button to the lockscreen through HTML on already modded lockscreens. Do you have to use Java and CSS too? I'm at a loss

Any one know how to do either of these things?

I found this: http://www.chinesecomputing.com/programming/java.html regarding the chinese in Java, but I haven't been able to figure it out.
