    Unicode - Some Example Code

    Can somebody give me some simple, basic example code that would write the first 5000 Unicode characters to a file? I'm using MingW (GNU GCC) and I absolutely refuse to learn Windows programming (not going to explain why), so it's gotta work with GCC.

    I tried this, and I think it's just writing ASCII:
    Code:
    #include <stdio.h>
    #include <tchar.h>
    
    int main()
    {
        wchar_t wc;
        FILE *fp;
    	
        fp = fopen("test.txt", "w");
    
        for (int i=0; i<5000; i++)
    	{
        	wc = i;
        	fputwc(wc, fp);
    	}
    
    	fclose(fp);
    	   
        return 0;
    }

    Here's a good guess:

    Code:
    int main()
    {
       wofstream file("out.txt");
       for (wchar_t ch = 0; ch < 5000; ++ch)
         file << ch;
    }

    Thanks, but it's a no-go. First, it says wofstream is undeclared (I included iostream, fstream, and tchar). Second, the actual numbers 12345678910111213...) get written to the file.

    How can the program output anything at all if you get a compiler error?

    If you changed wofstream to ofstream then numbers will get written to the file. If your compiler doesn't have wofstream then there's nothing to do.

    The example compiles for me (with fstream) and I get an out.txt file.

    haha...yea, I changed it to ofstream to make it compile.

    Are you using gcc (MingW)? With it, I get `wofstream' undeclared (first use this function). I'm including iostream, fstream, and tchar.

    What version of gcc are you using? I had to upgrade mine to make wide streams work.
