GUI toolkits often use Unicode internally, in which case, there isn't
a problem (so long as the user's font has a degree symbol).
For locale-based text (e.g. terminal I/O), this can be handled by the
message catalogues; strings won't contain a degree sign in a locale
whose encoding doesn't support it.
Obviously, this requires that you get the string from a message
catalogue in the first place.

This is available in "text" widgets, but not elsewhere (e.g. text
objects in a canvas widget, or labels).
Current versions of Tk use Unicode internally, but you need to use
"encoding system utf-8" before sourcing a UTF-8 script (by default,
scripts are read according to the locale's encoding).
