What if you remove the opener first? And then the closer? Will it try to 
find another opener then?

What about strings like

std::cout << "\
This is a\n\
multiline\n\
string.\
";

or

const char* s1 = R"foo(
Hello
World
)foo";

?

The latter being the case that many languages have to deal with: 
multi-line string literals.
