Text corruption in Ubuntu

I've had this problem before, and it's just popped up again. I forget how I fixed it last time. Here's the thing:

This is my blog posts draft file. It holds the posts I haven't yet posted or rejected, and I refer to it most mornings. It's not usually in Chinese. It's the result of the text editor reading the file incorrectly, and it seems to happen when I mix Windows and Linux line break characters in the one file. I've tried a few ways of fixing it now, and they seem to work, but fall down later. I guess I've got some more research to do.
