Hmm, that is weird! But I guess we should revert it and re-open bug 103765 until we find a better solution for since this issue is more serious than the other.

I reverted this commit locally (on Windows) and I still get the same buggy output, can someone else try locally?

This is weird.
I've just tried locally as well and the issue is reproduced while reverting the commit if it's done from the UI, however from commandline it's not.
Ie: instdir/program/soffice --headless --convert-to pdf /home/xisco/Baixades/test.odt --outdir /home/xisco/Escriptori/
Comment 9 Xisco Faulí 2017-11-08 15:02:02 UTC
Ok, I've bisected it again using the UI at export time and it points me to this commit instead:

Pass GlyphItem around
We have this nice structure that contains (almost) all the information
we need, so pass it around instead of passing separate fragments of said
information.

The ultimate is to kill the horrible sal_GlyphId hack if encoding
various bits of information in the higher bits of a 32-bit integer.

@Khaled, Does it make more sense now?

Yes, that makes a lot of since. I was expecting something around this area as it touched PDF export. Thank you!
