SSRS Reports and fonts

So when I add a textbox, the default font is Arial. When I look at any predefined textboxes in the report the font is Arial Unicode MS. If I chose to change the font to the default predefined textbox font, Arial Unicode MS, then I get an error.

So, I have a few questions?

  1. How is that font displaying if it is not on my machine?
  2. Why can I not choose a font that is already being used by other objects in the report?
  3. How can I fix this issue to get Arial Unicode MS font in the objects I add?
