Decrpyte this message

Okay, folks, here is a challenge. And a nice one at that. I've run into this code a lot. I'm pretty sure windows just doesn't know how to handle this code, but it is the basis of many, many foriegn-made game resource files. This particular segment is from a Korean made game, that I am hoping to modify for my own personal use. I know that someone, somewhere can decode this stuff for me or point me to the right tool. So with all of that said, I'll paste just a small section of the 6 MB text code, here:
