Thanks for your quick answer

I get question marks both in QDK and when I play the game. Also I tried defining a new verb containing diacritics; the verb seems to work in game - it does what it should do - but it displays question marks instead of diacritics.
Also I have the same problem when I try to create a new LDF file. I tried to save the file using both Unicode and UTF-8 encoding, but it displays strange characters in the program.
I uploaded an ASL file containing a single room, an object and a verb with diacritics.
