Format changes on 3rd page when combining multiple PDFs together

[Nicole3033407716zb]

When I combine 3 PDF invoices together, as well as a PDF email, the 3rd page format jumbles up, making it look like an alien language. This does not happen every single time, but I would estimate about 90% of the time. When the files are in Binder mode, it looks correct, but as soon as I print it, the format changes.

Ex: 8.5 X 11 10M 20# WHITE LETTERMARK COPY STATE OF NC

This is how it should look, but on the 3rd page, it looks like this:

8.K - 11 10I 20x G HfM, L, MM, ) I A)W ERPr SMAM, RF O

I have changed nothing, the writing should be the same for both.

This points to a problem with subset embedded fonts in one of your files. I wrote about this many years ago, and have documented a potential workaround: http://khkonsulting.com/2015/10/more-missing-characters/ - there is a link in the first paragraph to an earlier article that might also be relevant.
