Summary: Undisplayable glyphs on Wikipedia Product: Fedora Version: 9 Platform: All OS/Version: Linux Status: NEW Severity: medium Priority: low Component: pango AssignedTo: besfahbo@redhat.com ReportedBy: beland@alum.mit.edu QAContact: extras-qa@fedoraproject.org CC: fedora-fonts-bugs-list@redhat.com
I did a fresh installation of Fedora 9 using the network install method and adding Office/Productivity software in addition to the default set. I'm seeing undisplayable glyphs on the following pages:
http://en.wikipedia.org/wiki/Punctuation#Unicode http://www.wikipedia.org/ http://en.wikipedia.org/wiki/Phoenician_alphabet#Encoding
I would expect a default installation to be able to display all glyphs that appear in Wikipedia, so that readers can learn about them. Many non-English glyphs, even fairly obscure ones, are displayed properly, which is excellent. It would be nice to finish off the rest. I don't know if this is a flaw in Pango, if I would need to install additional font RPMs, or something else.
This is with firefox-3.0-1.fc9.i386 and pango-1.20.4-1.fc9.i386.

appear in Wikipedia
Well, Wikipedia will always have characters that cannot be displayed. Simply because it's always over the edge of what Unicode encodes, while a stable distro is a bit behind that.
Anyway, font issue.

------- Additional Comments From bl.bugs@gmail.com 2008-07-16 09:06 EST ------- We gladly accept patches for more glyphs at DejaVu :-) But I don't see us having a script like Phoenician really...
But I even doubt you could find a Free font for each glyph in Unicode.

------- Additional Comments From besfahbo@redhat.com 2008-07-16 09:25 EST ------- Let me also note that we are working on a feature for F10 or more realistically F11 to have a notification box pop up and suggest installing a font whenever a character cannot be displayed. That may well "fix" this bug.

------- Additional Comments From bl.bugs@gmail.com 2008-07-16 11:00 EST ------- I guess you can install a lot of fonts for all kinds of script to solve it for most scripts. For Phoenician, look at the Aegean font at http://users.teilar.gr/~g1951d/ for example (no idea if there are rpms available in Fedora). But don't expect to get *all* glyphs from Unicode (which defines approximately 100000 different characters) covered by your fonts.
In the mean time, I don't really see much point in distributing fonts for scripts like Phoenician by default...

They're not. New Fedora font packagers are of course welcome. http://fedoraproject.org/wiki/Ancient_Scripts_fonts

--- Comment #9 from Bug Zapper fedora-triage-list@redhat.com 2009-06-09 22:06:12 EDT ---
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

With Fedora 11 and firefox-3.5-0.20.beta4.fc11.x86_64, I'm still seeing undisplayable glyphs at:
http://www.wikipedia.org/ http://en.wikipedia.org/wiki/Phoenician_alphabet#Encoding
I didn't get any popup or anything saying that an additional font was necessary to display these glyphs; shouldn't I have?
I Googled "freefont sans", but it's unclear to me what I'm supposed to be looking for, Behdad.

This feature mostly works for gnome-based apps nowadays. Not sure what firefox uses. You should ask in

(@ben: adding Phœnician to dejavu would be nice though)

OK, I stand corrected, but still I think it is not an issue of Firefox. Changing component to the i18n to decide which languages we want to support in Fedora, per default or what to do about this part of Wikipedia.

No we don't have 100% coverage of wikipedia and probably won't any time soon, but the default font coverage is now good enough IMHO for most major languages that we can support.
If you want even better support best way is to contribute/ package free fonts and get them reviewed: the Fonts SIG is there to assist with that. :)
