Is it possible? I though there is no way out..
I'd suggest write chadz or Harald in IRC, for sure they will respawn him.
Of course there's a way out. The world doesn't end to the East of him, that's NA territory. He needs to go into NA territory (click viewing: EU and it will then move to NA side of the map) click move and select somewhere to his east to move to. Then he can re-enter EU territory north or south of there.
Thanks guys for advices, i contacted Harald via Pm, i'll wait for his answer.
There's nothing to wait for. You're not stuck, you are in EU land, but to get anywhere else in EU, you will need to go back into NA land and move north or south to re-enter EU lands.
Them's the breaks, i'd suggest you start moving and not wait for Harald to fix something that doesn't need to be fixed.
