I do use firefox, so that isn't the problem, I just looked at your web
page again, I am now seeing all the bracket symbols (I haven't done
anything different)
But they have a line space between them. I.e. the vertical bars appear
as three disjointed pieces. So, for example, a large left Bracket
appears disjointed. But at least its getting better, the browser is
finding the fonts.

| Subject: [Phys-l] math symbols and brackets in web pages
|
| Recently several people have reported (off-list) having
| trouble viewing some of the equations in my web pages.
| Here's the situation as I understand it:
|
| A) The tools that I use (notably HeVeA) have recently become
| much fancier. In particular, they can do an impressive
| (albeit not perfect) job of typesetting equations, including
| things like the big brackets around matrices and multi-line
| fractions.
|
| B) This has made me more motivated to use fancy equations in
| my html pages, and less motivated to prepare pdf versions of
| everything.
|
| On MS platforms, it appears that if you are having trouble,
| the fix is reasonably simple. My information about this is
| secondhand and somewhat sketchy, since I don't do MS windows.
| But here's what I've been told: There's a font issue on top
| of a browser issue:
|
| 1) You need to have at least one font on your system that
| provides the glyphs for the math symbols and brackets.
| Note that you do not need to use this font as your
| "standard" or "current" font; Firefox is clever about
| looking for "substitute fonts" when needed; for more about this, see
| http://www.av8n.com/computer/htm/encoding.htm#sec-substitute-fonts
|
| It appears that some MS systems already have such a font
| installed, so you might want to skip to step (2) and come
| back to this step if needed.
|
| If you don't already have such a font, you can install the
| code2000 font, which seems to have pretty good coverage of
| math symbols and brackets. It's shareware, so you can try
| it for free (and then pay $5.00).
| http://www.code2000.net/
|
| See also
| http://en.wikipedia.org/wiki/Free_software_Unicode_fonts
| for information about free unicode fonts.
|
|
| 2) You need to view the documents using the Firefox browser.
|
| If this is not already on your system, you can install it for free.
|
| The MSIE is apparently hopeless for a number of reasons,
| including the "substitute font" issue.
