What the requirement says

Natural language for text in page content shall be determined

Can it be fixed automatically?

Fixed by the automatic fix. Our automatic fix removed this failure in every test file where veraPDF reported it (measured 2026-10-24 with veraPDF 1.28.2). Run the free check to see the before/after result for your own file before paying.

How to fix it by hand

Set the document language before export (Word: Review › Language) or in a PDF editor's document properties (Acrobat: File › Properties › Advanced › Reading Options › Language). Passages in another language need their own language on the tag.
