How about non-character code points? They're just passed through per spec, but having them checked would be a good idea. How about overlong UTF-8 sequences (e.g. < U+0080 represented in 2-byte)? They'd be turned to U+FFFD, right? Oh, perhaps, fatal-flags.html would be a better place for overlong sequences. I mentioned it there. jsbell 2014/04/29 21:41:18 Good idea.
