Displaying ampersand in my product name

Hi,
I want to have ampersand in my android game name. But after build, I saw that ampersand(&) is replaced with _. What should I do in this situation?

I think is not possible to have symbols in names "·$%&/() … Only unmbers letters and _

I figured out the problem in an interesting way. I saw this other forum. Using a little bit thicker ampersand(&) instead of normal one(&) solved the problem. I have no idea how and why it solved.
