How to embed fonts in PDF with Nitro.
Nitro PDF Pro Windows
Embedding Fonts
To make a PDF accessible, it is important to embed the fonts as all users may not have the same fonts installed on their computers. If the fonts used in the PDF are not embedded, the document may not display as intended, making it difficult or impossible for some users to read or understand the content.

Setting the Document Language
Setting the document language is an essential step in making a PDF accessible because it enables assistive technology to understand and read the text correctly. It allows the screen reader to accurately pronounce the text, identify the language-specific characters and apply the appropriate hyphenation rules.

Marking a Document PDF/UA as Compliant
Once you have completed the task of making your PDF document accessible, run a check on the PDF/Universal Accessibility (PDF/UA) compliance using any PDF compliance validator. If your PDF document passed the check and it meets all necessary accessibility criteria, you can mark it as PDF/UA compliant.
