This option allows applications to receive unescaped strings
in their string callback. For such applications, this avoids
having them to escape the string in the string callback, which
saves some CPU/memory.
This includes a patch submitted upstream that tells YAJL
to not unescape strings before passing them to the user's
string callback function.
