More than likely no. Have you ever smelt sulfur? Any charred smell that may occur would quickly be overcome by the intense smell of sulfur no doubt.
I have, rotten egg. At times the smell comes out of the faucet in my bathroom for about 3-4 seconds when I first turn on the cold water. Yess, i know its not good. Then there was 10th grade earth science class. Sulfur smell, bong water smell, mix of both. Either way it smells, I would not want to stay around for it.
