I'm trying to cycle through a bunch of input shapefiles using a reader path as follows:

C:\\my_project\\my_data\\**\\my_shape.shp

However, some of the folders represented by ** contain characters from the Russian alphabet and this seems to be causing the reader to loop round and round without error or warning.

Is there a way of testing a path for unrecognised characters and skipping it?
