A completely useless factoid I just discovered.
I used the Windows character map to copy and paste a degree symbol (°) into my PC SMS application and sent it to my mobile phone. What arrived at my phone was the letters "Ao".
So for those of you wondering, you can't send a degree symbol via SMS.
Next time I will have say 2 deg not 2°
And another thing. The HTML entity for a degree sign is °
I just tried to add a degree symbol to an SMS message on my Nokia N900 and the number of characters used increases by 91! Surely that can't be right? Think I'll stick with the word "degrees" or as you say, deg.
