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);
