To get this to work, they had to typedef the string type to char*, which means the API will also accept any normal string and probably crash at runtime. So to get this little convenience feature, type safety was sacrificed.

Seems to me that it would also prevent tools like the address sanitizer and valgrind from detecting some invalid memory accesses (corresponding to negative indexes). A "more conventional" string library [1] might be safer.
