Hi all,

just some thinking around... you all know the Credits. It has a symbol in game. Where does that come from? Is it available in Unicode? Is there a "high resolution" image for me to see some details?
Is there some lore around this currency?

It is the old Brazilian Cruzeiro symbol and was chosen because: a) nobody uses it anymore and b) it looks cool as a credits symbol. It's represented in Unicode as U+20A2.
