How is Bash' code to store string of any characters should be containing pair of "" and '' at the same time explicitly, being exact verbatim so, ie. cannot be modified, escaped or etc, as expected from ordinary/naive human writing), into a variable let, eg., it be
*foo "foo" and 'bar' content* v="$(echo foo "foo" and 'bar' content)" v=$'foo "foo" and 'bar' content' ... so on its combination up >7 tries to no avail.. so help out solve
