Read UTF8 file with std and print strings to console

I'm so confused it is not funny.

Using VS2012, console project, the character set in the configuration is set to unicode.

The file is in UTF8.

I'm loading it with std::ifstream into a vector of std::string. The BOM is also taken care of and the bytes shown in the debugger match those in the file.

How on earth do I print this string to the console?

This line printf( "%s\n", line.c_str() ); only prints garbage.

Nothing special. Here is the complete code:

std::string line;
std::ifstream file( fullpath );

if( file == NULL )
{
    printf( "Error opening file\n" );

    return;
}

file.seekg( 3, file.beg );

while( std::getline( file, line ) )
{
    printf( "%s\n", line.c_str() );
}

Is there a reason you're using `printf` instead of `cout`? Anyhow, nothing is wrong with that line, can you post the rest of your code? – IllusiveBrian Aug 03 '14 at 02:55
And the terminal you're printing to can handle UTF8? – Some programmer dude Aug 03 '14 at 03:07
I'm using the Windows console. Why wouldn't it be able to print utf8? – Lara Aug 03 '14 at 03:11
@Namfuak cout also prints garbage, the exact same garbage actually. – Lara Aug 03 '14 at 03:14

Ok, ok. So what you guys are saying is that the problem is the console. If I were to run the same code on a windows application, there would be no problem. Is this correct? – Lara Aug 03 '14 at 03:21
"Is this correct?" You will have to convert UTF8 to the native Windows encoding which is UTF16 (or is it UCS2? Never sure with Windows), and use native wide-character Windows APIs. – n. 'pronouns' m. Aug 03 '14 at 03:24
Got it. Thank you guys. – Lara Aug 03 '14 at 03:28
