Sorry but I had no success. Following the instructions of the 
wiki-article the filename D:\wör\bf.vtk should be converted to 
D:\W_R\BF.VTK (all unknown characters replaced by an underscore). But 
the error still exists..the reader can't find the file.
VTK_ERROR - 2008-12-17 12:06:39 - NO_ERROR (0) reading file: D:\W_R\BF.VTK
VTK_ERROR - 2008-12-17 12:06:39 - CANNOT_OPEN_FILE_ERROR (20002) reading 
file: D:\W_R\BF.VTK
