This is the mapping code for string:

%MappedType string
#include <string>
     const char *s = sipCpp->c_str();
     return PyString_FromString(s);
         // Allow a Python string whenever a string is expected.
         if (sipIsErr == NULL)
             return PyString_Check(sipPy);
         if (sipPy == Py_None) {
             *sipCppPtr = NULL;
             return 0;
         if (PyString_Check(sipPy)) {
             *sipCppPtr = new string(PyString_AS_STRING(sipPy));
             return 0;
         *sipCppPtr = (string *)sipForceConvertTo_string(sipPy,sipIsErr);
         return 1;

It should just need string being replaced by std::string and 
sipForceConvertTo_string(...) renamed to 
sipForceConvertTo_std_string(...), but I'm not really sure about the 
naming scheme, so please try yourself, before I post incorrect code.
