'answer (there is a file it)' returns false after selecting a file

[Mark E. Powell]

Had to give up a project a couple months ago that was being derailed by a Rev bug that had no workaround. Was wondering if anyone can tell me if this is fixed in 2.9.  In the message window, I type the following

answer file "The prompt..."
answer (there is a file it)

This returns false if the file name contains certain extended ASCII characters, such as the Czech Ř (R with caron) or Ů (U with ring above) or Polish Ł (L with stroke).  

Can anyone confirm that this bug still exists in 2.9?  It is a deal-breaker.

Thanks.

Mark
