The issue is with your webserver … It includes
Content-Type: text/html; charset=UTF-8
when the actual character set of the page is ISO-8859-1
Use the control panel for your website to change the default character set to ISO-8859-1 and the degree symbol will show correctly.
Thanks Ken. I put a .htaccess (AddDefaultCharset iso-8859-1) file in my Apache 2.4/PHP server on the weather station computer (local access and testing) and that worked. The station web server is a LightSpeed server and I had to open a ticket but it was quickly resolved.
