sed replacing specific characters and control characters by escaping

Code:
sed -e "s/[\.\/\%'=:\(\)\`_\"\@\;\+\*\#\$\?\!]/ /g" old.txt > new.txt

While I do know some control characters need to be escaped, can normal characters also be escaped and still work the same way? Basically I do not know all control characters that have a special meaning, for example, ?, ., % have a meaning and have to be escaped to be replaced.

Does the above sed work as expected to replace all of the below characters with a space?
Code:
 ,
  .
  @
  /
  #
  :
  (
  )
  '
  *
  %
  $
  +
  ?
  _
  =
  "
  !
  ;
