1863314 - Tifinagh characters - unicode 2D30 - 2D7F - are not correctly managed (firefox 119.0, MacOS 10.15.7))

Status: RESOLVED DUPLICATE of bug 1803406

(Core :: Layout: Text and Fonts, defect)

Description

Attachment: TifinaghOnFirefox-2023-11-06.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/119.0

Steps to reproduce:

I type Tifinagh letters (unicode 2D30-2D7F) in input field of any form displayed on Firefox 119.0 / MacOS 10.15.7

Actual results:

Instead of displaying the right glyph, Firefox displayed either nothing (not even a space) either another Tifinagh letter.

Expected results:

On Firefox / IOS and on Safari / MacOS , the Tifinagh letters, previously entered on Firefox / MacOS, are correctly displayed: that should have happened also on Firefox / MacOS.

This file is the screenshot of a text entered on Firefox / MacOS with Tifinagh letters, as shown on Safari / MacOS: Tifinagh letters are rightly displayed

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I can't reproduce this on 14.1. https://www.wikiwand.com/fr/Utilisateur:B2g56 displays fine. Jonathan do you happen to be able to reproduce?

Reporter, if you can, it'd be great if you could figure out when this broke on your machine with mozregression.

It should take about 15 minutes or so on a good internet connection to run something like mozregression --good 115 -a https://www.wikiwand.com/fr/Utilisateur:B2g56 (assuming it worked on e.g. Firefox 115), and it'd help a lot. Thanks!

It doesn't reproduce for me, either.

My guess is that the reporter has a version of Noto Sans Tifinagh installed locally, and that this could be an example of bug 1803406.

B2G56, could you check if you have a copy of that font in your ~/Library/Fonts directory? If so, try removing it; macOS includes a copy with the preinstalled system fonts, and if you have another one in your own directory this can lead to confusion.

I deactivated the Noto Sans Tifinagh that I installed some days ago, and now everything is OK.

Thank you for your help. I could not imagine this issue was derived from this additional font.

Oh, great -- glad to know it's fixed for you. Thanks for confirming that.
(We still need to make Firefox less vulnerable to this kind of problem, but that's proving tricky...)
