If you run: > MOZ_DISABLE_PANGO=1 firefox you can view all the MathML sites correctly (albeit with that annoying Symbol dialog, i.e., #133709). A ye olde post here: http://mail.gnome.org/archives/gtk-i18n-list/2003-February/msg00042.html seems to say that Pango and MathML (Mango?) don't play nicely. Another out there says that Blizzard was working on a corrolary to this problem: http://lists.gnu.org/archive/html/lilypond-devel/2004-05/msg00084.html So, I guess you can't have both worlds right now. I suppose a "Disable Pango if you want to read math" statement is needed in rather BOLD letters at Moz/Firefox Fedora pages/release notes.

This is an update to a release (FC3) for which MathML support existed so release notes wouldn't make much sense. Breaking upstream features in an update does not seem a good policy anyway... >From the point of view someone writing MathML pages this situation is a total mess. It would be acceptable, but a pain, if one could detect from "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Fedora/1.7.6-1.3.2" that "This Mozilla MathML rendering has been broken for the sake of pango by your Linux distribution. Get a copy from mozilla.org". Come on: one can do something similar with IE with or without MathPlayer but not with Mozilla/Firefox with or without MathML support?! If the maintainer ever reads please consider (from the SPEC file I gather it was not intentional): -- reinstating MathML support in an update for FC3; -- making lack of MathML support for FC4 or FC5 and later detectable by dynamic pages; or get pango vs. MathML fixed!

[Bug 19066] Re: Pango-enabled firefox breaks MathML support
this is fixed for firefox 2.0 Only with Pango disabled, apparently - or better yet, not compiled in. I'm running Firefox 2.0.0.6 and have the following fonts installed: Math1, Math2, Math3, Math4, Math5 (from Mathematica 4.1), cmex10, cmmi10, cmr10, cmsy10 (from TeX), and Symbol. While the MathML torture tests from http://www.w3.org/Math/testsuite/ look great with Pango disabled, all kinds of strange glyphs appear instead of the expected rendering otherwise. I also have to point out that, when none of the aforementioned fonts is installed, MathML looks the same with or without Pango - and while it's not as good as the sample renderings, it certanly looks much better than with both Pango and fonts. -- Pango-enabled firefox breaks MathML support https://bugs.launchpad.net/bugs/19066 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I’m still getting pretty bad results even on Gutsy (2.0.0.3).

Freddy, just go to any site that uses mathml - search for mathml, for example - and make sure that pango rendering in firefox is enabled. If I recall correctly, pango is only used for firefox rendering now if there are certain language support packages installed which need the enhanced language support - in other words, the bug hasn't been fixed, but it won't show up for most users now. -- Pango-enabled firefox breaks MathML support https://launchpad.net/bugs/19066 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
