It is not UNICODE -- its just a character from a special font. If you print that out (see below) you will see that it has a decimal value of -105.

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
int main()
{
    char c = '—';
    cout << c << " " << (int)c << "\n";
    return 0;
}
int main()
{
    char c = '—';
    cout << c << " " << (int)c << "\n";
    return 0;
}

So in your program just check for a character whose ascii value is -105 and change it to --.

At least that's how it works on an American keyboard and Vista Home. Other keyboards might be different, I don't know.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

1. The emdash character has value '\x97' in most of Windows single-byte code pages (it's equal to -105 if char type is signed and 16*9+7 if it's unsigned). Look out! No emdash character in most of Windows so called OEM code pages. Alas, Windows console applications put/get OEM coded characters to/from its consoles, so you can't print this character or get it from the keyboard in console application (without some tricks, but it's the other story).
2. Type char* variable points to a single char or to an array of char, it does not contain any chars.

const char* pemdash = "\x97";
// Now *pemdash expression returns emdash character value
// See #1 above...
char emdash = '\x97'; // it's emdash in most of code pages...
const char* pemdash = "\x97";
// Now *pemdash expression returns emdash character value
// See #1 above...
char emdash = '\x97'; // it's emdash in most of code pages...
