degree symbol on eDLT

Hi there,
I am trying to get a degree symbol into a dynamic label (for an AC set point):

Format(targetDLTText, temperature:0:1, #$c2#$b0'C'); {°C in UTF8}
SetStringIBSystemIO("Label Group Text", "Local Network", "Lighting", "Study AC Setpoint", Variant1, targetDLTText);

if i run this the eDLT it displays A degree C
if i change the #$c2#$b0'C' to °C I get ?C
what is the correct way? obviously this is all about ascii. Unicode and UTF8...

Thank you
Mark

 

I did something similar to read the temperature from my spa via temp sensor
I realise its not the same but I do get °C shown on the eDLT
This is an extract of my code and comments inside my Wiser 2 logic

Within toolkit
1)set the tempsensor mode to measurement
2) give it an ID number
my one has 121) }

If GetBoolIBSystemIO("Measurement App Valid Value", "Local", 121, 1) then
begin
{ This line starts with the global variable for what we are going to display and equates it to the inbuilt system IO,
so now this global variable is the real value from the temp sensor}
Temp_Real := GetRealIBSystemIO("Measurement App Real Value", "Local", 121, 1);


{convert real value to a string}
Format (Temp_String, Temp_Real:4:1);

{label the string}
Append (Temp_String, '˚C');

{display the String}
SetStringSystemIO("Inside temp", Temp_String);

end;
