This exact issue has already been answered I don't even know how many times. So no, it HAS been talked about before NUMEROUS TIMES. You are simply wrong.
But, you know what, what's one more to add on to the pile? It's an issue of locale. Either change your computer's locale to Japan, use Locale Emulator or extract with Japanese name encoding assuming you have WinRAR.
Also, CHRIST those grammatical errors and spelling errors. I hope you're just ESL in progress, because if not, I'm going to start questioning whether you're even old enough to be here in the first place.
