I did this

cmd
"curl.exe" -o "ポ.html" "https://www.google.com/"

I expected the following

I expect to run this command and save "ポ.html"
But what was actually saved was "ダ.html"
("ポ" reads po. "ダ" reads da in japanese)
When specifying a path with the -o option, if "ポ" is included, it seems to change to a different character for some reason.
I have confirmed that this bug occurs in version 8.1.2_5, but not in version 8.0.1.
