I've only just started working with PDF generation, so I'm not very familiar
with the format itself to be able to understand it. Considering that Acrobat
Professional is able to generate a document that does work with the buggy
Firefox viewer, I assume there must be something in the PDF file that we could
do to make it work in Firefox.
I'm trying out all options, I've also posted to Mozilla about this issue.
However, if I can get the generated documents to work with the existing version
and old versions of this internal viewer, that would be an ideal solution.
Thanks very much for your help and advice.

custom embedded fonts
Given that the problem is FireFox - why not contact Mozilla and get them to fix
their bug??
Or, since pdf.js (their PDF renderer) is open source - go fix it yourself and
contribute the code??

Subject: [iText-questions] Problem with Firefox internal PDF viewer and custom
embedded fonts
Hi All,
We have been using iTextSharp for a while and recently ran into an issue with
the new internal PDF viewer in Firefox 22 and 23 (we think it goes back to v19
but don't have those versions to verify). If you open the attached iText
generated PDF file in Firefox with its internal viewer, you will find spaces in
the location where the 'g' and 'q' characters are supposed to be. All other
viewers we have checked display the text correctly (IE, Chrome, Adobe). If we
use Adobe's Acrobat Professional to generate the PDF, it works fine in Firefox.
The problem is in some way related to the custom fonts we are trying to embed
in the document. We have 6 different custom fonts we use, but only two of them
have the problem of missing characters.
I've also attached the working Acrobat generated document to compare against.
Looking for some help to identify what we need to do to generate the document
correctly for it to work with Firefox.
Thanks very much in advance!
