problem with symbol of degree

[Gunner]

Not really a solution, but based on some Googleing I found this link that states "The problem is being caused by UTF-8 bytes being interpreted as Windows-1252 (or ISO 8859-1) bytes"

I supose you could bandaid the issue by removing the degree symble from the source, if able.  Or else await the developer confirming if the display widget is the cause, or something else.
