1807042 - pdf displays incomplete when openend in Thunderbird (but OK in Firefox)

Status: UNCONFIRMED

(Thunderbird :: General, defect)

Description

[Chaos Prevails]

Attachment: aeco-el-select-b-nl.pdf

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0

Steps to reproduce:

1. receive an email with a pdf
2. right-click the pdf and choose "open"

I use the latest version of TB 102.6 on Ubuntu 22.04. This bug exists at least since Feburary 2022 when I received this email. Luckily it is immediately clear that information is missing.

I recently reopened the old email, and tested it in Firefox (108, latest), and Nextcloud (internal pdf.js v25 latest). Both show the PDF fine. But Thunderbird is not.

Actual results:

1. pdf is openend in a new tab, but information is missing

Expected results:

1. pdf is openend in a new tab and is should show all information

Hello,

I think I have found the reason. When opening the pdf, I see a lot of the following error messages in the console:

Warning: getPathGenerator - ignoring character: "Error: Requesting object that isn't resolved yet SofiaPro_path_T.". pdf.js:454:13
Warning: getPathGenerator - ignoring character: "Error: Requesting object that isn't resolved yet SofiaPro_path_A.". pdf.js:454:13

obviously SofiaPro is not installed, but yet it worked in Firefox. So in Settings -> Fonts & Colors -> Advanced -> Font Control, I checked "Allow messages to use other fonts", and voila, nothing is missing anymore!

I'm not sure if that is Linux related, and I'm not sure whether "allow messages to use other fonts" is unchecked by default. But it might be a good idea to allow "other fonts" at all times for PDFs (as e.g. the Firefox pdf viewer seems to do?)?
