Interesting thing is happening to a friend and his firm as they collaborate with an engineering firm based in China. Language is an obvious issue for project meetings and documentation. At a little deeper level how about between applications. Let's say using Navisworks and exports from Revit...
There is no translate option during export!
Seems to me the "solution" to sharing this is to use a common language for the modelling/software/documentation. Easier said than done perhaps to choose English as the "language of business"? What if the project is to be built in China? Better make sure you have native Chinese speakers on staff?
Architecture/Engineering work is increasingly international and multi-national, I imagine we haven't seen the last of this sort of thing.
