Create a string‐reference object having a valid `std::string` value, whose external representation begins at the specified `startIndex` in the specified `original` string reference, and extends either the specified `numCharacters` or until the end of the `original` string reference, whichever comes first. The external representation must remain valid as long as it is bound to this string reference. The behavior is undefined unless `startIndex <= original.length()`. Note that if `startIndex` is `original.length()` an empty string reference is returned.
