This code is there for a reason: standard read() cannot read unicode 
characters on the input (returns zero), so it would be impossible to enter 
a unicode filename in unicode mode without this code.

I would expect _fileno(stdin) to return zero, and mFileHandle to be zero 
as well, so that we call console_read, which should work.

Could you look into why console_read is not working on your platform? 
Thanks!

Cheers, Chris.
