RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 1 Tomas Popela 2023-03-13 09:54:58 UTC 
Is gedit or some other application able to display these characters or only Firefox and Thundebird are failing?

And last thing - can you please try to use upstream binary from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release (currently Firefox 110) and https://www.mozilla.org/en-US/firefox/all/#product-desktop-esr (currently 102.8) and let us know how it works there?

I don't have a test environment to run third-party programs.
Sorry.
Comment 8 Jan Horak 2023-05-05 08:58:00 UTC 
Jens, could you help with that? Is any specific font required for the new Unicode 15.0.0 characters? I've opened the page https://cnman.github.io/font/CJKUnifiedIdeographsExtensionH.html and copied the content to gedit and I still see the unicode numbers instead of characters.

Well it doesn't render for me even in Fedora 38...
Comment 10 Jens Petersen 2023-05-12 04:56:32 UTC 
Moving to google-noto-cjk-fonts

But I think this wait on upstream to support Unicode 15.
Comment 11 Mike FABIAN 2023-06-01 07:33:46 UTC 
I installed the font given in the first comment from http://cheonhyeong.com/File/TH-Tshyn-4.0.0.7z

i.e. now I see:

$ fc-match :charset=31350 file family style 
TH\-Tshyn\-P1:style=Regular,SiongKui,Ippan,Ilban,Thường,ChangGui,SoengKwhai:file=/home/mfabian/.fonts/TH-Tshyn-P1.ttf

Before installing that font fc-match did not find anything.

Now I can display U+31350 fine both in gedit *and* firefox in Fedora 38.

firefox-113.0.1-1.fc38.x86_64
Comment 12 Jens Petersen 2023-06-07 10:03:43 UTC 
Moving back to Firefox:

We suspect this requires backporting Unicode 15 support to Firefox ESR.
Comment 13 Tomas Popela 2023-06-07 10:54:43 UTC 
Mike, can you please test it on Fedora with the Firefox ESR - available from https://www.mozilla.org/en-US/firefox/all/#product-desktop-esr (to really confirm that it's a problem of Firefox ESR)?
Comment 14 Jan Horak 2023-06-07 11:11:57 UTC 
Unicode 15 is supported since FF 109, see: https://bugzilla.mozilla.org/show_bug.cgi?id=1792775
So if is it case of unicode 15, ESR 102 is affected. The ESR 115 should fix it for us.
Comment 15 Tomas Popela 2023-06-07 11:19:03 UTC 
Great, thank you Jan! Let me move this to POST so it can be tested once we move to ESR 115 (similar as with bug 2035779 or bug 2028942)
