The problem is that the HTML (and probably PDF) uses Unicode U+2212 ("Minus sign") as the subtraction operator; You can see this by searching for "−" in the HTML. Frama-C/Jessie does not accept this; they expect U+002D ("hyphen-minus") instead. I recommend that Frama-C/Jessie be changed so that U+2122 is permitted as an alternative to "-", just as many other Unicode characters are already accepted. In addition, the documentation should perhaps be changed to use "-" so that it will work with older systems that do not cut-and-paste this character correctly. On my system, the difference is a pixel or two, and is thus difference is rather hard to detect.
