Create a new or change your current Command Prompt shortcut to run:
"%windir%\system32\cmd /u"
"/U Causes the output of internal commands to a pipe or file to be Unicode"
and add "chcp 65001":
"%windir%\system32\cmd /u /k chcp 65001"
or set
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\Autorun
or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
to command
"@chcp 65001 > nul"
e.g.
> reg add HKEY_CURRENT_USER\Software\Microsoft\Command Processor ^
/v AutoRun /d "@chcp 65001 > nul" /f
