Chinese character in Url problem with Java

Question

I cut and pasted the following line in to my Firefox url field :

http://www.baidu.com/s?wd=你

This line was generated by my Java program.

The last Chinese char in the Firefox field sometimes became : %C4%E3 [ Correct ]

Other times it became this : %E4%BD%A0 [ Incorrect ]

I tried to cut and paste the url into IE. In the url field it shows up still as "你", but the result page search field shows the char as "浣", could this be a unicode-8 or unicode-16 problem ? So I'm a bit confused. How do I get the correct code "%C4%E3" from the char "你" with my java program ?
