Way to get unsigned char into a std::string without reinterpret_cast?

Question

I have an unsigned char array that I need in a std::string, but my current way uses reinterpret_cast which I would like to avoid. Is there a cleaner way to do this?

unsigned char my_txt[] = {
  0x52, 0x5f, 0x73, 0x68, 0x7e, 0x29, 0x33, 0x74, 0x74, 0x73, 0x72, 0x55
}
unsigned int my_txt_len = 12;

std::string my_std_string(reinterpret_cast<const char *>(my_txt), my_txt_len);

Answer 1

Have you tried sstream?

     stringstream s;
     s << my_txt;

     string str_my_txt = s.str();

Answer 2

Use the iterator constructor:

std::string my_std_string(my_txt, my_txt + my_txt_len);

This is assuming that you want the unsigned chars to be converted to char. If you want them to be reinterpreted, then you should use reinterpret_cast. That would be perfectly clean, since what you say is exactly what is done. In your example, though, it doesn't make any difference.
