KF-PDF-POLICES: Some fonts are not embedded
This code shows up when an electronic invoice is validated. Here is what it means, why it fires, and what to change in the file.
Why this code appears
One or more fonts do not travel inside the file. This is the leading technical cause of PDF/A non-conformance: an archival document must display identically on a machine that does not have the fonts of the one that produced it.
How to fix it
Turn on font embedding in the PDF export. Watch out for the so-called standard fonts (Helvetica, Arial) that some libraries deliberately omit: in PDF/A they must be embedded like any other.
Where it happens
This check is ours, not a code from the standard: we do not cover enough of EN 16931 to borrow its numbers, and a misattributed official code would send you to fix the wrong field. It concerns PDF.
