Why do Unicode Encoding issues happen? 

The Status Dialog Box in CommonLook PDF, indicating a failure for Unicode encoding issues.

There are a variety of reasons why you may get an error message telling you that your document has Unicode, or character encoding, issues. Some possibilities include:

  1. Fonts are being used that are not, or cannot be, mapped to Unicode.
  2. How the PDF is being generated from the source.  

What do you do when Unicode Encoding issues happen?

Possible options include:

  1. Try using different fonts that are encoding correctly.
  2. Try generating the PDF a different way and see if that corrects the encoding issue.
  3. Convert the PDF to a Word document and then back to PDF. (Caution: This may change the physical view including fonts, graphics, layout, etc.  In addition, links, form fields, and other interactive elements will likely be removed!)
  4. Try "Fix Font Issues" in Acrobat with the Pre-Flight tool.
  5. Delete the tags and retag the document in Acrobat.
  6. Run the document through "PostScript" in Acrobat and then convert it back to a PDF.
  7. Find someone who can fix mapping/encoding issues. (Note:  This can be a very technical and labor-intensive process.  Using the options above might be better.)
