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
