Attachment: Another example without mfenced

Actually, it seems it is not related to mfenced.
This example shows formulae that use two different characters for "|". Only one is well-rendered.

Can you provide the output of "fc-match --sort Symbol | head -n 5",
and "grep -iw symbol /usr/lib/iceweasel/res/fonts/fontEncoding.properties" please?

fred@debian:~$ fc-match --sort Symbol | head -n 5
s050000l.pfb: "Standard Symbols L" "Regular"
Vera.ttf: "Bitstream Vera Sans" "Roman"
DejaVuSans.ttf: "DejaVu Sans" "Book"
DejaVuSans-ExtraLight.ttf: "DejaVu Sans" "ExtraLight"
DejaVuSans-Bold.ttf: "DejaVu Sans" "Bold"

fred@debian:~$ grep -iw symbol /usr/lib/iceweasel/res/fonts/fontEncoding.properties
# If you have Symbol (Adobe) type 1 font, keep the following lines 
# commented out (you do NOT need them). However,  with  truetype Symbol 
# Symbol font
encoding.symbol.ttf = Adobe-Symbol-Encoding
encoding.symbol.ftcmap = mac_roman
# TeX's Computer Modern fonts (Roman, Math Italic, Symbol and Extension)

Note: I haven't got the problem with Iceweasel, but with the CVS version of Firefox.

Thanks for this.  Some lines have been uncommented here, but given you don't have a "Symbol" font, that won't be the problem.

The cvs 1.8.1 branch version?  Or does bugzilla insert these and are they unrelated to the version where you see the problem?

Try resetting font.mathfont-family to the default, if that has been set.

(in "about:config")

Comment 9

[Frédéric Wang (:fredw)]

The version I used for the test is "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008050412 Minefield/3.0pre" but I reported the bug with Iceweasel.

This bug disappears when I set the font.mathfont-family string to use STIX fonts so you may ignore it.

Hmm. It seems as if there wasn't anything checked into the browser code to fix this.  (So nothing was broken.) It looks like a configuration issue.
