Invalid argument on Greek file name (and other Unicode characters?)

[metheofanis]

I run whisper.exe from Windows.
If I give a Greek file name, I get the error below. If I rename the file with English characters, it works as expected.
Kindly note the last line. Greek characters are presented as ????
I've tried to change the console codepage to Unicode without success.
Any help?
