Letters 'i' and 'j' miss dots in PDF exported from MS Word 2016 (2.040R-ro)

[llvs]

The title already tells the whole story:
Letters 'i' and 'j' miss dots in the resulting PDF which is exported from MS Word 2016 with the built-in save as functionality.

• Downgrade to release 2.020 works
• Release 2.040 works using Adobe Acrobat PDF generation
  Cheers,

Could you please attach such a PDF to this issue? Thank you.

I see just now that colons in the time column on the left hand are also missing.

I have tried unsuccessfully to reproduce this using both Mac and Win versions of Word 2016. Any additional information about setup might be useful.

[llvs]

We could reproduce it on two Windows 10 (v1803) machines before downgrading. Word and Windows both use latest patch levels. Other than that, I don't know what special item our setup might include.

Also here: OTF or TTF?
@llvs Could you please try the opposite format of the one you’re using? It may be that Windows still is better with TTF in some cases.

[llvs]

I am quite sure, that we had the TTF installed, as we know that OTF often poses problems in Windows, especially with MS Office. If I find the time, I can try OTF, however I assume that it is not better than TTF.

All right, thanks! It’s tough on this end because QE couldn’t reproduce the problem at all. I do know however that Word’s built-in PDF tools may cause problems sometimes. See an example of that here:

You may want to try using the Adobe PDF “printer”:

Reproduced on this end. Step-by-step:

• install Source Sans Pro Regular 2.040 TTF
• create new Word document in MS Word 2016 on Windows 10.
• paste the text 9:15 Arbeiten Kic projekte

option 1

File → Save as… → PDF
result: colons, dots on i and j are missing

option 2

File → Print → Microsoft Print to PDF
result: colons, dots on i and j are missing

option 3

File → Save as Adobe PDF …
shows Adobe Sans fallback font

workaround

All above options work properly when using the OTF font.

@erniemarch Found the problem by using MS Font Validator. The maxComponentElements value in the maxp table is set to zero (instead of 3).

This was caused by an oversight in the ttfcomponentizer adobe-type-tools/afdko#710

Thank you all for investigating and fixing this!

Fixed fonts haven't been issued yet. Let's keep the issue open until then.
