I've done quite a bit of chinese titles in FCP... you have to mess with the international input settings on the mac to switch to foreign keyboard input. It works, but it's a pain. Easiest way is just to create them in photoshop and bring them in as a jpeg or psd...
Thanks Kai,
I switched the international settings a few days ago and the text in the title generator would switch automatically. Today it isn't doing it. WTF!!?
