Sort of in agreement with Minipp here.
I am a bit more knowledgeable about this, though.
Language packs have absolutely nothing to do with DR.
If you're computer can read the symbols, then they will translate them appropriately. If not, it will show up as jargon. Whether you're in a game or not doesn't matter.
If you want to cover your bases, install Jap / Mandarin simplified and traditional language packs. Or find an asian language pack. I'd find one for you, but I'm at work and really.... it's not that hard.
