Thank you for your post and screen shot.
Keep in mind that the Classic Theme was deprecated in FileMaker Pro 14 and removed in FileMaker Pro 15. Therefore, you should move any layouts that use the Classic theme to another built-in theme.
Your file is damaged. When I try to use the Calibri font on any layout, it gets truncated when saving to PDF. When I create a new file and use the same fields, font, and layout options, everything performs as expected. I have enclosed the sample file.

Thank you for your valued inputs.
Not sure how the file got damaged. I checked the file you sent and the junk character issue is not happening there.
But I observed that, you have used Enlightened theme. As I already mentioned, this issue appears to be occurring for 'Classic' theme.
From your inputs its looks like we will have to change all the layouts from Classic theme to some other theme.
