I was using a method that jumped through hoops using some printf nonsense in order to put the result of the brace expansion into an array, I removed it from the answer because list=( {' '..~} ), as in ilkkachu's answer would Just Work; this is an alternative (worse) method.

If I understood correctly:

for c in {' '..~}; do list+=($c); done

Some notes:

  • There's no need to quote ~ in the brace expansion;
  • Technically what's printed and stored is just a subset of ASCII (it excludes non-printable characters).
