> What logging does when UnicodeEncodeError is happened?
Hm, it seems logging does best job, show enough information to stderr.
But sometime, Python is embedded in web servers and there is no stderr.
pythonw.exe may not have stderr too....
I still feel backslashreplace is better default error handler. But it's not
strong opinion and it shouldn't block this issue. Go ahead.
$ cat x.py
import logging
logging.basicConfig(filename="mylog.txt")
msg = "hello, はろー"
logging.error(msg)
$ LC_ALL=en_US.US-ASCII python3 x.py
