I have successfully generated an installable package with jpackage. All seems to work as expected.
My problem is that the Greek characters from my License.txt file are not readable as you can see in the picture below.
I don't know if it is relevant but I will mention that:
When the package is created from CMD I add
--java-options -Dfile.encoding=UTF-8but this made no difference.Also, my Java application can read-write Greek characters from files, database and from http-restful.
I tried to add a License.html file with HTML code inside with no success

Thank you very much in advance.
