Spacing of displayed integral limits in luatex is poor

[juliangilbey]

Please see this luatex bug report where I provide examples of how lualatex produces very poor limits spacing when typesetting integrals in display style.

Hans suggests that it is a lack of appropriate OpenType kerning information; I don't understand the details here, but I have noticed that XeLaTeX is able to typeset the integral without difficulty.

I don't know whether this is easy to fix or not.

Thanks!

It is a LuaTeX bug, the font works fine in XeTeX and MS Office.

OK, thanks, I've reported it back to LuaTeX.
