Combining PDF documents results in unprintable characters
Problem: when combining multiple PDF files into one PDF, the result will be a variety of unprintable characters.
1) EACH individual PDF file appears fine (both on the screen and when printed). There are NO unprintable characters within the PDF.
2) CAN combine say 5 to 15 PDF files. All Fonts & characters appear fine (within the combined PDF). WILL also print OK. NO unprintable characters.
3) Now try to combine about 35-60 PDF files into ONE PDF file (NOT good). The COMBINED PDF will display on the SCREEN unprintable characters ( = square box) on nearly every page!
Occurs RANDOMLY throughout many of the pages.
4) Fonts are Arial & Verdana. All Arial fonts show as embedded. Only the Verdana BOLD shows as not embedded (but it is a system font, so who cares).
5) REMEMBER: EVERY individual PDF will appear OK & Print OK.
SMALL numbers of combined PDF's will appear OK & Print OK.
ONLY when many PDF's are combined does this problem appear!!
6) Happens to multiple people in our office environment. All running Windows 10 (with latest patches), and Acrobat Pro XI (11.0.20)
7) This is NOT a printer problem!!!!
You can see all the square boxes on the SCREEN when viewing the "combined" PDF files.
8) Plenty of system memory. Plenty of Hard drive space.
9) CAN you FIX it! (say YES Adobe CAN!!!)

We have the same problem. When combining multiple PDF files, Arial Narrow shows as square boxes. Even we download these fonts, they aren't showing up. Can you fix it ??!
