unable to use a "degree" symbol in xml

Question

I don't know why but I'm unable to use a "degree" symbol (°) with xml Text. I tried with ° but it doesn't work. Output is just like this

Heart Rate: 78, Respiratory Rate: 102<12, Temp (degF): 70°
, Oxygen Sat (%): 100.Non-invasive Blood Pressure: Systolic: <107, Diastolic: &51 Mean: 70

Answer 1

Use ° or ° (same as °).

This will convert it into degree. See the unicode character page for details.

Answer 2

Use UTF encoding. Also, there is no °-entity in XML.
