I am having problem showing the celsius symbol in my sitemap:
Item file
Number Heating_LivingRoom_Setpoint "Temperature Set Point [%.1f °C]" <temperature> (Temperature, Group_LivingRoom)
Sitemap file
Setpoint item=Heating_LivingRoom_Setpoint icon="temperature" minValue=1 maxValue=30 step=0.5
It seems that your sitemap file was created with a wrong encoding. Please try to change the encoding to UTF-8.
Did not help changing to UTF-8 
Also when doing refresh the value of setpoint disappears, is this a persistence problem?
Could you perhaps try converting your items file to UTF-8 as well? This helped me with “my” celcius signs…
@hakan That did the trick!!
