As they say, if you think that's horrible, your life must be sweet
indeed.
Let's not let perfect be the enemy of good enough. If coping with
unescaped double quotes is an issue, use
printf '"%s" ' "${vals[@]//\"/\\\"}" ; echo
instead to get a little farther. If you already have escaped double
quotes, then you don't need it.
If you can use this approach to get the problem solved, then use it.
If not, try something else -- another tool, if necessary.
