How to change the name of a civilization in LUA?

I want to create a little mod which changes the names of civilizations at the start of certain eras. For example: Persia becomes Iran in the industrial era. Gaul becomes France in the Renaissance and so on.

I did a lot of research but I could not find a way to change the name of a civilization during the game.

Before the game would be in SQL such as:

Code:

UPDATE Civilizations SET ShortDescription='Iran' WHERE Type='CIVILIZATION_PERSIA';

Or I would change the localized texts in SQL.

From what I read, it looks like the game database can not be changed during the game. Is that true? Is it possible to change the localized texts?

The Lua-event would be:

Code:

Events.SerialEventEraChanged( g_iCityEra-1, g_iCurrPlayer );

But how can I change the name of the civilization in the event handler??

Thanks for any help!!
