When formatting a position in DMS format on the Instinct Crossover and Venu Square 2 like this:
var dms=posn.toGeoString(Position.GEO_DMS) as String;
The degrees symbol in the string shows up as Unicode 57520, hex 0xE0B0 instead of decimal 176.
This happens in the simulator in SDK 7.4.3.
I didn't test every device but others I tried do not have this problem.
