If switching to zsh is an option:

~$ IFS= read -r string
asd 'qweq asd' qweqwe
~$ print -l ${(z)string}
asd
'qweq asd'
qweqwe
~$ print -l ${(Q)${(z)string}}
asd
qweq asd
qweqwe

So:

IFS= read -r string
array=(${(Q)${(z)string}})

Or to preserve empty elements ('' ""):

array=("${(Q@)${(z)string}}")
