Title: [SOLVED] Draw "not standard" char
Post by: GabrielS on June 13, 2013, 10:13:52 pm

Hello,

I want to draw some unusual characters like Ω. I know it is possible because when I do like this :

text.setString(L"Ω");

It works.
however, I want to do something much more like this :

string newText="blablaΩΩΩ";
text.setString(newText);

( Sorry for not putting the 'code part' not in between good tag but you can see just above that I had some issues displaying Ω in [ code ] tag. )
This displays '?' instead of 'Ω' . Is that possible to cast a string as a "L string" ? If so, how shall I do this ?

Thanks,

Gabriel

std::wstring = L"blablaΩΩΩ"

Or directly use sf::String. By the way, as far as I know, the compiler isn't required to accept characters apart from ASCII directly in source code. For portability, you might therefore need the \x, \u or \U escape sequence.

hi,

Thanks for the fast answer.
However, std::wstring can't work for me because I'm using method needing 'std::string' argument.
I wanted to try with \u, it works, but I get the same character : instead of Ω , i get a '?' char

string resistorUnit = "M";
        resistorUnit.append("\u03A9");
        //mResistor->drawIn(window,font,"MO",COLOR_RESISTOR);
        mResistor->drawIn(window,font,resistorUnit,COLOR_RESISTOR);

If that is your code or you can change it, change it to use sf::String, if it's outside code, does it support UTF-8, if not, you're not getting that ohm symbol in there.

Ah perfect, I managed to use sf::String correctly !

Thanks for the responses.
