A while back I adopted a suggestion by Eryk Sun and installed ConEmu
on my Windows 7, and now use it in place of cmd.exe.  Interestingly,
it apparently provides UTF-8 support where cmd.exe and PowerShell do
not.  I just tested it with your two examples in cmd.exe, PowerShell
and both of these shells accessed via ConEmu.  Interesting!  Thanks,
Eryk, for making me aware of this program!
