Hi Eric,
I don't think this type has a Length1 since it's subtype is CIDFontType2, so it would have to be validated differently.
re: Subtype name (Required) The type of CIDFont; CIDFontType0 or CIDFontType2.
A CIDFont dictionary is a PDF object that contains information about a
CIDFont program. Although its Type value is Font, a CIDFont is not actually a
font. It does not have an Encoding entry, it cannot be listed in the Font subdictionary
of a resource dictionary, and it cannot be used as the operand of the Tf
operator. It is used only as a descendant of a Type 0 font. The CMap in the Type 0
font is what defines the encoding that maps character codes to CIDs in the
CIDFont. Table 5.13 lists the entries in a CIDFont dictionary.
TABLE 5.13 Entries in a CIDFont dictionary
KEY TYPE
Happy Holidays,
William

Hi,
I looked quickly at this issue.
My first impression is that the PDF isn't a PDF/A because some entries of the Font Stream are missing ("Length1" for exemple).
If I bypass this control, I have others problems about this font (WMode inconsistant in the CMap and Missing Glyph)
Monday, I should have more time to work on this issue.
Regards,
Eric

[jira] [Resolved] (PDFBOX-1195) Font Validation Problem

Eric Leleu resolved PDFBOX-1195.
--------------------------------
Resolution: Fixed
This issue is fixed.
PDF file is now considered as PDF/A by preflight.
Here the list of changes :
- Remove useless control in the CIDFontType2 validation. (length1 entry)
- Check the WMode value to know if the WMode is missing from the Dictionary, if it is missing use 0 as the default WMode
- manage the CIDToGID map stream.

Hi Eric,
This is a strange font. Calibri (Embedded Subset) of Type: TrueType (CID) with Custom Encoding.
I had also bypassed the "Lenght1" control getting the WMode error return.
Happy Holidays,
William
