People have asked for this before. One issue is that there'll be a slippery-slope of everyone else wanting their local money sign added. Euro, British Pound, Brazilian real, Russian ruble, Japanese yen, Indian rupee, Ukrainian hryvnia, Bitcoin, Swedish krona, Swiss franc, South Korean won, Turkish lira
With that said, I personally wouldn't mind some Euro support, seeing as it's one of the most traded currentcies in the world.
