Characters? Japanese has around 2200 characters. Warcraft 2 can accept only 256 characters? The PS2 version of Warcraft 2 does has a Japanese version though.
I see, here's also a DOS-version with Simplified Chinese support. I mean that required some sufficient modifications. Original war2 uses 1-byte chaset, that means your can use an alphabet up to 255 characters or a little less.
That's very unfortunate. Is there someone able to modify the original war2 to support more chars? If so, Chinese and japanese or some Asian languages would be feasible to take action.
