Corrupt text

[nevh78651100]

Someone help me!  I have completed a PDF document which was perfect until I saved it. Then the text became corrupted. This happened once before months ago and it seemed to fix itself somehow. I am on Mac 10.13.05 And am using Acrobat Pro DC 2018.011.20040

I am desperate that I have a solution as this is a very important document.
