Hm, interesting. There is only one place where the UTF-8 to UTF-16
conversion code is called in case of parsing a file identified by
name or a URI and that is the code that converts the file name/URI
to UTF-16. So the only reason why this exception would be thrown is
if the file name string was invalid.
In your case what immediately comes to mind is the possibility that
the layout_filename and topology member variables are initialized
in the wrong order. In this case you would be using layout_filename
which hasn't been constructed yet and would therefore contain
garbage which, in turn, would most likely trigger the exception.
Can you confirm that layout_filename is declared before topology
in KanannotateHelper class?
