File "C:\python\python310\lib\encodings\cp1252.py", line 19, in encode

UnicodeEncodeError: 'charmap' codec can't encode characters in position 295-358: character maps to <undefined>

This non-fatal error is confusing and has led to BFs (BF-33486) that incorrectly point to this as the source of failure. Even though benign, marking as P3 given the painpoints to the log-scanning layperson.

I think this amounts to literally changing

self.file = open(filename, "a")

to

self.file = open(filename, "a", encoding="utf-8")

inside buildscripts/resmokelib/logging/handlers.py.

This is in Resmoke utilities, which belong to my team of Correctness, but julian.edwards@mongodb.com, since you recently implemented this via SERVER-77561 (and we have very tight bandwidth), would you mind following up? This may also require backports.
