Arial/Times New Roman/NimbusSan Fonts not displaying correctly with Adobe Acrobat DC on Windows 10
I have a document that is over 600 pages. I wrote the document using Adobe Acrobat DC. I use the latest vesrion of MS WORD to create the index pages (ONLY) then copy the created pages into the document. Other than MS WORD to create the index, I use Adobe Photoshop (latest version) for all the images. Thereofore the 600 page document only has images (.png) from Adobe Photoshop and MS Word is used for Index ONLY. The rest of the written document was manually typed in via Adobe Acrobat DC.
Evey once in a while Adobe Acrobat DC gets weird and displays the text incorrectly and I must select the text and toggle the BOLD on and off to get the text to display properly. Can some one help me figure out why this document is doing this? Attached is the Adobe DC document which I had to fix manually. Attached are screen shots of how the text looks when this problem hits. The Ariel font seems to be the font with the problem. I use mixed fonts in this document. Any help would be appreciated. This problem is really annoying because I do not know which Arial text will be affected (changed to text that is partially displayed) in a 600 page document. Most of the document is written in Arial font and this problem does NOT affect all the text written in Arial font. It affects different text each time the problem shows up. So the error is not repeatable. Very annoying. I NEED HELP figuring this out and how to fix the problem so it does not come back.
Thanks, JoAnn Manges
