Hi Dan, 

Thank you so much for your quick reply. 

The font used is Gibson. It does happen with every document. 

I've attached the screenshots of the settings. 

Thanks so much for your help!

Hi everyone, 

Every time I try to export a Publisher spread in pdf, I get a pdf filled with strange characters as you can see in the attachments. 

Any idea what causes this?

Thank you very much and best!
