That's the problem as Ulrich pointed out.  ISO C says:
       Byte input/output functions shall not be applied  to  a
       wide-oriented   stream   and   wide  character  input/output
       functions shall not be applied to  a  byte-oriented  stream.

You have to use freopen between the calls - or use only wide stream
functions,
