To create a string with a whole swag of special chars in it, including '
do most of the specials inside 's then when you need a ', close the quoting 's
then put the required ' inside "", eg.

ff='+-_="'"'"
echo $ff

Hard to read at first but works.  This trick comes in very handy when trying to
get the correct quoting inside awk code inside a shell script.
