And what if the example is changed to be:

   ifstream file("local8bit.txt");
   istreambuf_iterator<char8_t> begin(file), end;
   std::copy( begin, end, back_inserter(str) );

? This use case is common, so you have to provide something like
"local8bit_back_inserter", and then to be explicit it's better to provide
