Well, not sure if it something that can be solved, but 1.8 is breaking books:
Pages in books that reach the maximal number of letters and include special signs (/,*') or colors get messed up, it mostly occurs in copied books even more.
My guess is that the max length that allows the text to be input has been set as the same as the length of the finished book, but including the code, similar to how in html you'd need to use "/" for some signs(if I recall).
Really not sure if you can do something about that, if you do, it'll save me hours of rewriting the broken books :S
