Couple basic questions….

I am working with a Game Hosting company and we are just starting to do some testing of Unreal Tournament on the Linux platform. I have everything working but am looking at a couple of small snafu’s that I need some help with.

1. Linux does not display ascii characters in game(ie: ?, …) is there anything that can be done to linux so that it will like the characters?

2. I run the servers with the nohup command. Is there a gently way to bring the nohup’d process down?

3. I want to clear the nohup.out file every 12 hours. I can schedule via cron, but was wondering what the best way to empty the file out was, without deleting it.
