Related to Core bug 120198 comment 85?
Same problem in SeaMonkey 1.5a, Gecko/20060531. This is NOT a Firefox-specific bug. It's a MathML rendering bug (MacOSX-specific, AFAIK). I suggest changing Product to "Core" if you want to get some attention to it.
What worked for me was to add the line:
\u00AF = \uFFFD\uFFFD\uFFFD\uF8E5\u00AF # ad-hoc: overbar is stretched with the radical extender
to the file
Four months later, and the status of this bug does not seem to have changed. The solution (which has been verified to work in Firefox, SeaMonkey and Camino) is in the previous comment.
That line comes from the mathfontSymbol.properties file.
Any reason why the Symbol font is not working for you guys anymore?
It could be that Symbol is not terminating the font.mathfont-family pref.
font.mathfont-family: ..., Symbol
On MacOS, one needs to change the default value for font.mathfont-family to omit the Computer Modern fonts from the list.
There was a time (not that long ago) when Symbol was not working on MacOSX. So I, at least, had eliminated it, as well.
did, indeed, fix the problem for me.
The instructions at
need to be corrected, then. Either that, or one needs to add the line I suggested about to mathfontMath4.properties, so that those who follow these instructions will not be tripped-up.
Math4 does not contain the overbar or radical extender, so it is not quite clean to put that definition in mathfontMath4.properties (the definition is only working because we further do some extra lookup in the Gfx font code to substitute glyphs not in the primary font).
The section "TeX's Computer Modern Fonts" on the font webpage instructs looking at: https://bugzilla.mozilla.org/show_bug.cgi?id=134849#c10
But based on this feedback, it might help users to just put that pref inline in the font webpage to make it more apparent.
The text in the font webpage has been updated. I am marking this one fixed, but we are not done yet with ‾ (bug 289678).
