The degree sign does not require unicode; it is in the normal ISO/IEC 
8859-1 or latin1 table. Every editor should be capable to display it. 
Every system should be able to enter it.

The degree sign "°" is under windows reachable via <alt>0176.

The masculine ordinal indicator "º" via <alt>0186.

The currency sign "¤" via <alt>0164.

So: there is no such problem.
