How to display chinese characters in output file of a concurrent program in oracle ?

[pradvin]

I'm working for Taiwan operating unit where supplier name is store in traditinal chinese language. I have written a package in which I'm displaying these chinese supplier name in fnd output file of a concurrent program. But in output file I see ? (question marks) instead of chinese characters.

So can anyone tell me how can i output chinese characters? is there any setups to do ?
