Can someone show me how to display special symbols characters using QLabel? Especially the degree symbol?

For example, I want to display latitude in terms of degree, minute, second like

Latitude: 70* 34' 30"

and replace the * with the actual degree symbol:

70, 34, 30 are 3 different double values

so in C++, it's kinda like:

double degree, minute, second
string = "Latitude: " + degree + "*" + minute + "'" + second """;
cout << string;
