I'm using C++ on windows and I'm trying create some code that will allow me to input and Unicode character code, then output that character to the console. I'm well aware of the issues associated with Unicode and the console, however that is not the problem I'm trying to fix.

What I have tried:

So far I have some code that will print out the character, if given the code before hand.
C++
int main()
{

    

    _setmode(_fileno(stdout), _O_WTEXT);
    
    wprintf(L"\u0004"); // A Unicode code should go in there as a variable.



    return 0;
}


I know how to output the character if I enter the code into L"\u(numeric code goes here)", what I'm looking for is a way to insert a variable code in there. I hope this makes sense.

This should work
C++
const wchar_t * wstring = L"some wide string";
wprintf( L"%s\n", wstring );
for a string. For a single character try this :
C++
wchar_t wideChar = 0x1234;
wprintf( L"hex: %04X  char: %c\n", wideChar, wideChar );

variable isn't a unicode character - it's string of 4 characters.
You would need to convert that to a wide character before you output it, and that means you need to think about what that string represents: a number, a value, a hex value, or what?

At the moment, you question is pretty much meaningless - you need to stop and think about what you are trying to achieve, instead of just diving into code.

Sorry, My question was not clear enough. I know how to output the character if I enter the code into L"\u(numeric code goes here)", what I'm looking for is a way to insert a variable code in there. I hope this makes more sense.
