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, 

The recent patch catches a couple of instances of ‘°’ that I missed back
