What steps will reproduce the problem?
1. Create change in a file that contains Form Feed control character. Make the change BELOW the FF character.
2. Submit review request.

What is the expected output? What do you see instead?
ReviewBoard diff viewer highlites wrong row.

What operating system are you using? What browser?
ReviewBoard is running on Linux. Using Windows7 + Chrome for viewing review requests. Our source control system is SVN 1.7.8 (Windows).

Please provide any additional information below.

Our codebase is ancient. It seems to contain some control characters (besides CR and LF) for example in C source files. ReviewBoard diff viewer seems to struggle with them, I have so far identified at least Form Feed (FF) control character to cause problems. Change highliting gets displaced by one line per FF. When the FFs accumulate, the highlited part can get pretty far from the actual change. See attached picture. I also attached the actual diff.
