Unfortunately I am able to show few of them while others appear as white box. I have read that this depends by the font installed on my computer. On this topic I am very confused. I have two questions:
1) is there some specific font Upp compatible that let me show most of the graphical characters (I need circle/square full/half white/black colored and some arrows);
2) What will happen to other users of my app if he does not have the same font?
If this is not possible within Upp I'll try to work with HTML document.
