I don't think that using the degree symbol instead of something like [deg] or [degree] in source code (message texts or comments) is a good idea because the degree symbol is part of the extended character set which depends on code page currently selected by the user, and thus may be displayed correctly, or not.
As mentioned in NEWS, TZDB commentary has been using been using some UTF-8 encoded characters since release 2018d. The set of characters used has included ‘°’ (U+00B0 DEGREE SIGN). This doesn’t seem to have been much of a problem, as widespread support for UTF-8 has largely obsoleted problems with 8-bit encodings that rely on extended character sets and code pages. See, for example, <https://en.wikipedia.org/wiki/Popularity_of_text_encodings>. The recent patch catches a couple of instances of ‘°’ that I missed back in 2018.
