Strange. It's possible the syntax highlighter is getting stuck on the UTF-16 surrogate pairs. Does it happen if you change the language to plain text before pasting in? alternatively try pasting in the decoded version (you can get it by replacing 'eval' with 'throw' in dwitter)... if the later still causes it to hang then It must be attempting to evaluate it!
