I'm just download the demo version to try out before buying. Anyone know if the character is transferable if I move on to the paid version?

I see many people recommending Tonberry server but it's based in JP, yes? Since I study in the UK, I'm wondering if it'll be a wise choice to be registered in that server. Will I have high latency due to the distance? Sorry, been ages since I've played MMORPG.
