You don't need any spaces, commas or symbols. In fact the degree, minutes and seconds symbols may cause problems if characters are used to display them which Google Earth doesn't understand. This can happen with coordinates copied from some websites.
In your example jmharris4 you can use any of the following:
47° 42' 09.83"n, 10° 56' 19.47"e
47 42 09.83n, 10 56 19.47e
47 42 09.83n 10 56 19.47e
I hope it helps.
