in thread Unicode UTF16 - Unknown encoding error

OK, I'm not that familiar with PerlApp, but it looks like you may need to explicitly tell it to include Encode - something like:

perlapp myscript.pl --add Encode

You may also need to add Encode::Unicode (and possibly others) if Encode delegates its Unicode-handling to more specific modules (as I suspect it might).
