Problem with FileIO

Hi All.

In Director exists the command "mapchar()" like Authorware.

My problem is: the linked txt appears right in windows but the file
(created in windows) that I reads with Macintosh appears demaged (char
like "??" ; "??" ;"??" ;"??"... became like a square!).

With Authorware I used "mapchar(1)" , but I don't find the solution with
Director!!!. Ther's anyone that can help me!!!

Thanks in advance,
Matteo
