PDF/UA-1 rule 7.21.6-2: A non-symbolic TrueType font encoding does not define a correct mapping to the Adobe Glyph List

Not fixed automatically font

What veraPDF reports

A non-symbolic TrueType font encoding does not define a correct mapping to the Adobe Glyph List (Encoding = %1, Encoding entry contains a Differences = %2, Differences are Unicode compliant = %3)

veraPDF rule 7.21.6-2 = ISO 14289-1:2014 clause 7.21.6, test 2, checked on PDF object PDTrueTypeFont.

What the requirement says

All non-symbolic TrueType fonts shall have either MacRomanEncoding or WinAnsiEncoding as the value for the Encoding key in the Font dictionary or as the value for the BaseEncoding key in the dictionary which is the value of the Encoding key in the Font dictionary. In addition, no non-symbolic TrueType font shall define a Differences array unless all of the glyph names in the Differences array are listed in the Adobe Glyph List and, if the font program is embedded, it shall contain at least the Microsoft Unicode (3,1 – Platform ID = 3, Encoding ID = 1) encoding in the 'cmap' table

Can it be fixed automatically?

Not fixed automatically. This failure needs the authoring tool or manual remediation; the automatic fix does not change it.

How to fix it by hand

Fonts are fixed at the source: export the PDF again from the authoring application with all fonts embedded (most office tools have an “embed fonts” or PDF/A option), or use a preflight tool that embeds missing fonts. Editing the PDF metadata does not change fonts.
