The string data returned by Location.toGeoString() contains the degrees symbol, which appears to cause problems when rendering text in the simulator for the 920XT for each of the fonts in FONT_XTINY, FONT_TINY, FONT_SMALL, FONT_MEDIUM, FONT_LARGE, FONT_NUMBER_MILD.
I realize that there are issues with entering non-ascii characters into Eclipse, but this issue is different in that it seems to work for some fonts on this device and all of the fonts on the other devices. I'm fairly certain that this issue affects applications that are run on the 920 as well.
