As I have wandered around Eorzea, I have noticed that all of the signage is in English, though written in the Eorzean font. With a few moments, I can usually puzzle out what any particular sign says.

This morning, I found myself wondering: I have the English version of the game software installed. If I had, say, the German version, would the signage all be in German but using the Eorzean font? If not, what does that say about the language actually used in Eorzea?
