I know this same question/error's been posted a million times and has been around for at least a decade. There's a number of possible causes and fixes, but none have worked for me.
Essentially, I open a PDF (unknown who produced it or how much it's been modified since then), but on some computers I get the error "Cannot find or create the font 'ArialMT'. Some characters may not display or print correctly.", while on others, I get no error dialog at all, but some text is just white boxes while other text (even within the same word or even just a closing bracket (i.e., ']') shows up fine:
From digging into the issue, I understand that some version/variation of a font wasn't embedded when the PDF was created, but what I don't understand is why I can open the exact same PDF in various PDF applications and some of them are able to display the entire PDF without any issue. To wit:
Adobe Acrobat Pro DC (2021.005.20060) - White boxes
Adobe Acrobat Reader DC (2021.005.20060) - White boxes
Nitro Pro (188.8.131.525) - No problems whatsoever
Unfortunately, the individual experiencing this issue (in addition to me being able to replicate it) is basically required to use AAP and can't use anything else due to <waves hand around> "reasons".
I ran the document in question through PreFlight and of course it finds a host of issues (font name is not unique; font not embedded; font reverts to .notdef glyph; text cannot be mapped to unicode; etc.).
Confounding the issue even further, I'm able to open the PDF in question just fine in Adobe Acrobat Reader DC (in addition to Nitro PDF) on at least one other computer. O' Consistency, whyfor dost thou detest me so!
So my questions are thus: Am I essentially boned on being able to get Adobe Acrobat Pro DC to open this PDF without issue, or at to display everything correctly and, if not, why does it open (and print) correctly with Nitro PDF (of which I'm not typically a fan, but it seems a mite less ... complexified than AAPDC)?
Any advice/guesses/suggestions/etc.? (Many thanks for any help!)
P.S., I'm not able to upload the PDF in question as it's (A), company-sensitive info and (B), 401 pages, but I may be able to hunt down a similarly affected document that would be postable.
Hope you are doing well and sorry for the trouble you are experiencing.
As described you are unable to view the PDF properly in your system and getting the square boxes.
As correctly said, it is the font issue as the font is not properly embedded in the PDF file or it is not present on your computer system. Please try the following preference settings and see if that works for you. Go to Edit (Win), Adobe Acrobat (Mac) > Preferences > Page Display > Under rendering, check use local fonts and click OK and reboot the system.
Also, you may ask the creator of the PDF file to create the PDF using Adobe Acrobat Pro DC and see if that helps
Also the third party apps use their own PDF mechanism to display and render the PDF content and they are not Adobe dependant.
Hope this information will help
Wondering if you could help me too.
I have the same issue but "Use Local Fonts" is checked...
Does this mean that it is a problem with the creation of the file rather than the viewing of it? If so, where in the PDF printer do I fix this? Just Print as image? Anything else?
We are sorry to hear that. Is this a neavior with a particular PDF file or with all the PDFs? Please try with a different PDF and check.
What is the workflow/steps you did to crreate the PDF file? Please try to recreate the PDF file from the orginal source file and see if that helps.
I have a theory on this one: The font I had this issue with is a font that Adobe licensed in the 1990's, but no longer does. I believe they may use this function as a licensing control mechanism.
"Use local fonts" was already checked for me as well with the same issue.
A work around I found is to right click the PDF file and select "Open with"> "Google Chrome" which displayed it correctly. Then I printed to a new PDF file which looks normal. Trying to redownload it from the Chrome screen did not work.
