Text changes to special symbols with saving PDF in Acrobat

To embed fonts in a PDF...

First, the ideal method is to embed them when the PDF is made (ie, saved as a PDF or exported to PDF) from the source document (ie, Word, PowerPoint, Adobe InDesign, etc.). Look at the conversion options, settings, or preferences to set the conversion to embed the fonts.

If you're dealing with an existing PDF, you can embed the fonts using Adobe Acrobat Pro. NOTE: This process should work OK if you have the same fonts on your computer system that the author had when the PDF was made. However, if the author used a special font or a special character that is not on your system, then it won't work for that portion of the PDF.

1. Open the PDF Standards tool panel (if it's not already in your right-side tool set, then open it via the Tools Tab in the upper left of the Acrobat window).
2. Open the PDF/UA Standards section.
3. From the Profiles tab, select the blue wrench in the upper menu bar.
4. Expand the Document section.
5. Select the Embed fonts utility and then click the FIX button in the lower right (has another blue wrench in the button).

Open the Preflight panel from the PDF Standards tool.

Run the Embed Fonts utility from the PDF/UA profile.

Hope this helps.
