Now nonprintable characters are shown by default. You can turn it off by using "wrench" button on the right side of ruller. But, it is uncomfortable. My solution here is to add option "nonprintable_characters" that will base on this concept, but in addition offer better user interface.
More information about implementation you can find in diff file.
