I think you're right, we don't assume anything when writing json
strings, so it's not going to be utf-8 (or die) if the path is also
not valid utf-8. The good thing is all this could be done in just one
place, append_quoted_string(), if someone needs too. I'll just go
document the fact that we may produce invalid UTF-8.
