Si empty() rendements false, le pointeur est telle que la plage de [data(); data() + size()) est valide et les valeurs qui y correspondent aux valeurs stockées dans la chaîne. Si empty() retours true, le pointeur est un pointeur non nul qui ne devrait pas être déréférencé. (avant C++11)
Original:
If empty() returns false, the pointer is such that the range [data(); data() + size()) is valid and the values in it correspond to the values stored in the string. If empty() returns true, the pointer is a non-null pointer that should not be dereferenced. (avant C++11)

Original:
The pointer is such that the range [data(); data() + size()] is valid and the values in it correspond to the values stored in the string (including the additional null character) even when empty() returns true. (depuis C++11)
