I think loadstring() may be the simplest solution.

you may need to use double quotes for the string, and you should quote
all double quotes inside the string .  Using single quotes is the
same.

Use [[ and ]] are not recommended, since it cannot be quoted and will
have security problem when used with loadstring().
