error in creating PDF files in Polish

[JanisBe]

Hi
First of all, let me congratulate you great job done with the script! it's really amazing!
I'm currently translating it to Polish (we have only 1st , 2nd edition, Empires, Seaside and Intrigue) and during printing pdf I found out that polish diacritic symbols are printed as black squares. I'm not a Python developer but I managed to find that here you left Times instead of previously used Minion fonts family. When I changed it to use Minion Regular, it all works perfectly.
I was unable to add my work as polish package, so I disguised it as italian. Here's git repo for it, you can add it to your translation db.
Best regards and once more kudos for great job!
Janis

Thanks, but I honestly won't have time to add contributions not formatted as a working github pull request. If someone else wants to do the work to transform this in a PR, feel free!
