Streaming output to save things - c++

Question

I would like to << stream to save all inputs from console into a file
Here is how I tried
ofstream of("file.txt");
while(1)
{
string str;
cin>>str;
of<<str;
}
I don't see the non-English characters in the file (Edit: I mean they are Japanese, Chinese or Korean etc)

Answer 1

You could stream char by char. Then it would be a true binary copy.
ofstream of("file.txt");
while(1)
{
char c;
cin>>c;
of<<c;
}

Answer 2

Streaming using the formatted extraction operator is a poor choice. Specifically, it will consume all of the white space.
If it were me, I would copy using std::getline or istream::rdbuf:
std::getline:
// Copy standard input to named file, one line at a time.
#include <iostream>
#include <fstream>
int main (int argc, char **argv) {
std::string s;
std::ofstream of(argv[1]);
while(std::getline(std::cin, s)) {
of << s << "\n";
}
}
istream::rdbuf:
// Copy entire standard input stream to named file in one go
#include <iostream>
#include <fstream>
int main (int argc, char **argv) {
std::ofstream(argv[1]) << std::cin.rdbuf();
}

Just a couple of points as a starter:
ofstream of("file.txt");
If you want to see Japanese, Chinese or Korean character you should not be using an ofstream here. You want a stream that writes wide characters: a std::wofstream. You will also haveendow that stream with a locale. See Why does wide file-stream in C++ narrow written data by default? for details.
Another point: You apparently are have a using namespace std;. You can find many questions here at Stack Overflow that indicate that this is a bad idea. Typing those extra five characters isn't very hard, it avoids problems with names from the standard library polluting your namespace, and it makes the code clearer.
while(1)
Your loop doesn't have any break statements to escape the loop, so this plus the while (1) means your program will never stop. It is just going to keep on going and going and going and going. You want it to stop (or should want it to stop) on encountering an error or end of file in the input stream.
A better approach is to use a construct such as
while (std::getline (std::cin, s))
to control the loop (except you need to use something special to get wide characters).
