As I posted on the issue, I don't like this approach. Unfortunately I
didn't spot the patches for another 7 hours. We've replaced a mysterious
missing line with an even more mysterious failure to highlight at all.
We should instead filter out the problematic non-printing characters; a 
browser's not going to usefully display them or reliably cut and paste
them anyway.
