Thanks!
I'm having problems with input of special characters. The Engine I use (Löve2D) had Problems with non-standard-english characters in the past, and the version that fixes it has not yet been released officially.
So I need to build the source of the engine and somehow distribute it along... which is somewhat of a hazzle. But once that's done, the update is on its way, and then the game can truly be played with any wikipedia version there is.
