Elaborate on what?

Indeed, it seems to. Unfortunately, your sample code uses a string
containing only letters, instead of a more interesting input.
hobbit:~$ string=$'abc \t\n\n\'"\\'
hobbit:~$ [[ $string =~ ${string//?/(.)} ]]
hobbit:~$ declare -p BASH_REMATCH
declare -a BASH_REMATCH=([0]=$'abc \t\n\n\'"\\' [1]="a" [2]="b" [3]="c" [4]=" "
[5]=$'\t' [6]=$'\n' [7]=$'\n' [8]="'" [9]="\"" [10]="\\")
So... what was your question?
