Thanks for your post.
Unfortunately this is an issue with ANSI scripts, we already have a bug open for this case (SC-4198). You should be able fix this issue by encoding the scripts differently, but it seems that you cannot choose the script encoding through the UI. - I have just logged this as a bug with SQL Packager (SPA-505).
However, you can set the script encoding if you run Packager from the command line. You will be able to use your UI project file with the addition of the /scriptencoding option.
Something like: SQLPackager /pr:"MyProjectFile" /makeexe /scriptencoding:Unicode
You can find out more information on using the command line interface in the helpfile:

I hope this is helpful.
