I am wondering why I have for most of my default fonts more than 1 file (for example "arial.ttf" and "arialbd.ttf"). I can see that the first one includes the default one and the second the bold one... but how does it work with SFML's setStyle() function? I mean, when loading a font, I specify only one file (propably arial.ttf), how can this become bold? It will propably don't look for a different file than, so does it a kind of to-bold conversion itself? What would happen, if I choose "arialbd.ttf" as the file and the regular style?
