Here the situation run xfreerdp against two hosts (whatever the windows version
is) 
Try a copy and paste from one host directly to the second one
The resulting text is ��chinese�� 

If you open a text editor on your linux box, and then copy first host text to
this editor, then select and copy it again and paste to the second one
the text is correct.

Sample on first host :
This is a sample text written down on a windows 2012 server
that need to be pasted on a windows 7 computer.

Result on the second one
���������������������������������������������������������������������������������������������������������������������������������������������������������������

Expected : same text and same data.
