[Webmath] mathml: cannot view the brackets (,),...

[kyanh]

Hello all,

Please forgive me if this message (mathML realated) bothers the list.

I installed succesfully MathML fonts for my browsers (flock, bon echo / 
firefox in Current Arch Linux, http://archlinux.org ). My setting in 
prefs.js:

    user_pref("font.mathfont-family", "Math1, Math2, Math4, Symbol");

I note that the brackets (and similar things ) arenot displayed 
correctly (see images).

Could you please help me fix this problem?

Thank you so much!
