[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 1221 bytes --]

To following code doesn't work with non-ascii characters in UTF-8: 
 
#include <iostream> 
#include <string> 
#include <locale> 
#include <clocale> 
#include <fstream> 
 
using namespace std; 
 
int main() 
{ 
  setlocale(LC_ALL, ""); 
  locale loc(""); 
  wcin.imbue(loc); 
  wcout.imbue(loc); 
 
  wifstream fin("test.txt"); // contains the UTF-8 string "ett smörgåsbord\n" 
 
  wstring s; 
  while (fin >> s) { 
    wcout << s << L" "; 
  } 
 
} 
 
This will print: "ett sm ". 
Now substitute "while (fin >> s)" for "while (wcin >> s)" and do: 
"echo 'ett smörgåsbord' | ./test", this will work as expected, printing: 
"ett smörgåsbord ". The problems seems to be in wifstream (the same problem is 
present in wfstream).
