Lets look at this from a slightly different angle. This is going to be a simulation style of game play. During the "Age of Sail", many people spoke different languages, dutch, french, spanish, and english, along with a host of others. As much as I dislike trying to read through a bunch of different languages to spot my own. I don't think a game of this nature should be restricted to a single one. What we can do however is ask the devs for advanced chat options. Like group tabs, or delegated channels.
