This doesn't just "recapture" the text, it also quotes it.

This unquotes the text partially before printing (because print is
invoked without -r).

This is fine. You can verify that the content is as expected:

    print -r -- $array2

Note that array2 is a scalar and not an array. array1 is an array with
one element. If you want array2 to also be an array with one element,
do this:

    array2=("$(eval "$@")")

Roman.

P.S.

Use `typeset -p var` to see the value of parameter `var`.

    typeset -p array2
