[vtkusers] vtkSTLReader does not accept foreign characters in filename

[R K Shyam Prakash]

 Hi,
      I had posted this question to the list a few days ago. I did not
receive any reply. Can somebody help me with this. Following is the
question. 
	I am using vtkSTLReader to read the STL files in my application.
Suppose my stl file has a foreign character in the path, then that
character is ignored and I am not able to read that file. For example if
the stl file path is "D:\STLFiles\ myüfile.stl" the character "ü" is
ignored by the vtkSTLReader. Is there any workaround for this problem?
 
Thanks,
Shyam
