VC++, the Spar Compiler, and G++ all seem to support it fine:

#include <iostream>
#include <string>
using namespace std;
int main() {
   char* s = "abcd\0efth";
   string str(s, 9);
   cout << str <<endl;
   cout << (int) str[4] << endl;
}

You do have to be careful because there are a few places where the string things
are converted to/from "default" terminated strings.  Like some of the constructor
choices and c_str();
