When I run this program:
-------------------------
#include <cassert>
#include <cstdio>
#include <fstream>
#include <iostream>
#include <string>

unsigned char data[] = {
  'd', 0xBC, 0xD2, '\r', '\n',
  'e', 0xB2, 0x7B, '\r', '\n',
  'd', 0xBC, 0xD2, '\r', '\n',
  'e', 0xB2, 0x7B, '\r', '\n',
  'f', 0xB2, 0x7B, '\r', '\n'
};

void write_it( char* name)
{
  FILE* out = fopen( name, "wb");
  assert(out);
  int count = 0;
  for( unsigned i=0; i<sizeof(data); ++i) {
    assert( EOF != fputc( data[i], out));
    count++;
  }
  assert( !fclose( out)); 
  cout << "Wrote " << count 
       << " characters to the file " << name << '\n';
}

void read_it( char* name)
{
  ifstream in( name);
  assert( in);
  cout << "Reading....\n";
  string s;
  for(;in>>s;) {
    cout << s.size() << "  " << s << '\n';
  }
}

int main()
{
  write_it( "temp");
  read_it( "temp");
  return 0;
}
----------------------------

I get this output:
------------------------
Wrote 25 characters to the file temp
Reading....
3  d+-
1  e
--------------------------

So it looks like string input from 
a file cannot read some character sequences.
Is this expected and desired behavior?
Or is it a bug?
