So you don't ask for JSON encoded objects but JSON encoded *and*
HTML/JavaScript embeddable escaped literal string.  That's simply not the
job of a JSON encoder.  That's another level of encoding/escaping
producing something that is not JSON anymore, so why do you want to ask a
JSON encoder to deliver it?

This is a feature/function you should find in a HTML templating library.
