There is no need to detect anything.

string_ref is defined like so

string_ref::string_ref(const char* s) : ptr(s), size(strlen(s)) {}

And it's like this by design.

string_ref doesn't even have construction from an arbitrary range in 
N3334. But if it were to be added, the behaviour wrt string literals 
would need to stay the same.

The fact that you can't tell apart an array from a string literal using 
types is irrelevant.
