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!

This is the Tummy.com rebuild for FC4 and for whatever reason, the problem seems to be fixed. I don't want to change the status until I have FC5 running, but maybe a FC5beta/Rawhide runner can check this? Of course, Bug 133709 is *still* unresolved. I really, really get annoyed by that Symbol dialog.

The RPM was built off the instructions here: https://www.redhat.com/archives/fedora-devel- list/2005-November/msg01244.html and what do they say to do: remove the Pango/Cairo bits. Aw nuts, I was hoping all was well. Oh well, I guess I'm on the other side of the Mango mess now, good math, bad languages. And, of course, it works with some sites that just go nuts with Fx 1.07 (Iron Sudoku, say).

That's the expected behavior. It also has a little optimization, dropping an strlen. The rest of the MathML was not working simply because Pango was refusing to choose font/shaper for Private Use characters. That was a one-line fix. With that, it only was not rendering the THIN SPACE character. That's this bug: http://bugzilla.gnome.org/show_bug.cgi?id=145275 I also worked around it by making Pango choose font/shaper for space characters too. All this is in Pango 1.14.1 that is in Rawhide already. With these, I get Pango render the MathML Torture Test exactly like the Xft backend. I even changed Pango to use a fixed 96 dpi resolution and got an image that had only 14 pixel differences with the Xft one, and those are minimal antialiasing differencing for the letter Pi.
